In a 2025 DigitalCommerce360 report, 76% of B2B e-commerce sellers and 27% of retail e-commerce businesses surveyed reported actively looking to replatform.

Why? 

To stay competitive, deliver better user experiences, and unlock new growth opportunities.

Website migration is no longer just an IT decision; it’s a strategic business move that directly impacts growth, UX, and marketing performance. Whether moving to a faster platform, upgrading to advanced features, or aiming for better integration with modern marketing tools, migrating your eCommerce website could be your most brilliant move this year.

But migration isn’t just about flipping a switch. When done right, it can elevate your brand. Doing it wrong can lead to traffic losses, broken links, and unhappy customers.

Quick Stat: In 2025, 28 million eCommerce sites exist worldwide, a 2.9% increase from 2024. This indicates rapid growth that pressures platforms to support scaling businesses.

Why Do Businesses Perform eCommerce Platform Migration?

Replatforming your eCommerce website isn’t something businesses do lightly. It’s often driven by growth, limitations, or the need to future-proof operations. If your current platform is holding you back, migration might be the best step forward.

Here are some of the most common reasons brands choose to migrate their eCommerce websites:

1. Outgrowing Current Platform Capabilities

As your business scales, you might find that your current platform lacks the flexibility or advanced features you now need, whether it’s multi-currency support, better inventory management, or advanced promotions.

A 2025 report notes that 60% of eCommerce businesses using outdated platforms (e.g., older versions of Magento or WooCommerce) cited limited scalability as a primary reason for migration to platforms like Shopify or BigCommerce, which offer better support for multi-currency and inventory management.

2. Need for Better Performance and Speed

A slow-loading website can kill conversions. Modern platforms offer faster, more optimized frameworks that improve user experience (UX) and SEO rankings.

A 2024 study found that a 1-second delay in page load time can reduce conversions by 7%, emphasizing the importance of speed.

3. Improving User Experience (UX)

An intuitive, mobile-optimized, and visually engaging website is critical today. Sometimes, a redesign on a more flexible platform is the best way to achieve this.

In 2025, 88% of online shoppers say they won’t return to a site after a bad UX, and 70% of eCommerce revenue now comes from mobile devices, driving demand for mobile-optimized platforms.

4. Expanding Integration Options

Growing eCommerce brands often need seamless connections to CRMs, ERPs, automation tools, and advanced marketing platforms. Some platforms offer richer ecosystems for these integrations.

Shopify’s ecosystem, with over 8,000 apps in 2024, supports 45% more integrations than legacy platforms like osCommerce, driving 30% of migrations among mid-sized retailers.

5. Enhancing Security & Compliance

Security is a non-negotiable. Migrating to a platform with better built-in security features, SSL, PCI compliance, or GDPR support can reduce risk and liability.

6. Managing Costs More Effectively

Some legacy platforms require high maintenance costs or expensive custom development. Modern SaaS platforms (like Shopify Plus or BigCommerce) often reduce total cost of ownership.

7. Unlocking Better SEO and Marketing Tools

Your platform should support your growth efforts, not limit them. Many migrate to platforms offering superior SEO features, customizable URLs, headless CMS capabilities, or built-in marketing automation.

Platforms like Shopify and BigCommerce saw a 35% increase in adoption among brands prioritizing built-in marketing tools (e.g., email automation, abandoned cart recovery) in 2024-2025.

Quick Stat: According to recent data from Statista, global eCommerce sales are projected to surpass $8.1 trillion by 2026, up from $6.3 trillion in 2024.

Planning an eCommerce website migration is about setting your business up for long-term success. Before getting into the technical details, laying a solid foundation is crucial. 

That starts with two essential steps: clearly defining your migration objectives and selecting a platform that aligns with your business goals. Get these right, and the rest of your migration will be much smoother.

1. Set Clear Objectives Before You Migrate

Migrating your eCommerce website is a strategic business decision more than a technical one. Without clear objectives, migrations can quickly become messy, expensive, and frustrating. Setting clear goals gives your migration direction and ensures every decision, from platform choice to feature prioritization, serves your larger business growth.

Here’s why setting objectives should always come first:

Keeps Everyone Aligned

A website migration impacts crucial business verticals like marketing, sales, operations, and customer support. Different departments often have different needs and expectations. By clearly defining the why behind your migration, you create a single vision that keeps all teams moving in the same direction.

Helps Measure Success

How do you know if the migration was worth the time, money, and effort? By setting goals early, you’ll have clear success metrics to track after launch. These could be faster site speeds, increased conversions, lower bounce rates, or smoother backend workflows. Without objectives, “success” becomes subjective.

Drives Smarter Decisions

Throughout the migration process, you’ll face choices: which features to prioritize, which platform to use, and how much customization is necessary. Your objectives guide those decisions, making sure you stay focused on what moves the needle for your business.

How to Define Your Migration Objectives

Knowing why you’re migrating is only half the equation. The next step is to translate that “why” into specific, actionable objectives. 

These objectives will act as the blueprint for your migration strategy, helping you make smarter choices about platforms, features, design, and integrations.

Start with the Problems You Want to Solve

Ask yourself and your team:

▪️ What frustrations do we have with the current platform?
▪️ What’s stopping us from growing?
▪️ Are there features we wish we had?

Identifying pain points will reveal the business gaps that your migration should address.

Connect Business Goals to Website Functionality

Your website is the core of your customer experience. Think about your larger business goals and map them to specific website needs.

Business Goal	Migration Objective
Grow sales in international markets	Add multi-currency & multilingual support
Improve marketing ROI	Integrate advanced analytics and customer tracking
Increase conversions	Simplify site navigation and streamline checkout
Reduce operational workload	Automate order management and integrate with CRM

Focus on the Key Areas

Here are some common focus areas for defining your objectives:

Performance Improvements

▪️ Faster load times = better user experience
▪️ Mobile optimization to tap into mobile shoppers
▪️ Reduced site downtime during traffic spikes

Enhanced User Experience (UX)

▪️ Clean, intuitive navigation
▪️ Easy product search and filtering
▪️ One-click checkout or guest checkout options

Operational Efficiency

▪️ Streamlined backend processes for order management
▪️ Inventory syncing with warehouses or suppliers
▪️ Automation for routine tasks like invoicing or emails

Marketing & Analytics

▪️ Better SEO capabilities to boost organic traffic
▪️ Advanced tracking for user behavior and conversions
▪️ Personalization features to offer tailored recommendations

 Cost Management

▪️ Reduce ongoing development or hosting costs
▪️ Move to a platform with lower transaction fees
▪️ Balance between upfront investment and long-term savings

Make Your Objectives SMART

Whenever possible, define Specific, Measurable, Achievable, Relevant, and Time-bound objectives.

For example:
❌ “We want a better website.”
✔️ “We aim to reduce checkout abandonment by 15% within 6 months of launch.”

Some Practical Objectives to Refer

Here are some practical examples based on real-world business needs to help you better understand clear migration objectives. These examples will show you how to turn vague ideas into actionable goals that guide your entire migration process.

Example 1: Boost Conversion Rates

Objective: “Increase conversion rate by 20% by redesigning the checkout flow and reducing friction points.”

Why it matters: If your analytics show that many users drop off during checkout, this goal gives your migration team a clear focus—optimize speed, reduce form fields, offer guest checkout, or integrate more payment options.

Example 2: Expand Into New Markets

Objective: “Add multi-currency and multi-language support to enable expansion into Europe and Asia by Q4.”

Why it matters: Selling internationally requires a website that feels local to customers. By making this a priority, you can ensure that your new platform supports localization features, relevant payment methods, and region-specific tax rules.

Example 3: Improve Website Performance

Objective: “Reduce product page load times to under 2 seconds across all devices to improve SEO and user experience.”

Why it matters: Speed matters—not just for keeping users engaged, but also for better search rankings. With this target in mind, you’ll know to prioritize faster hosting, image optimization, or choosing a platform with lightweight, performance-oriented themes.

2. Choose the Right Platform for Your Needs

Migrating your e-commerce website is about moving your business forward. And that progress depends heavily on choosing a platform that fits your goals, customers, and future ambitions.

Why Platform Choice is Crucial

Choosing the right e-commerce platform is one of the most important decisions you’ll make during a website migration. Why? Because your platform doesn’t just power your website, it powers your entire online business. Every interaction your customers have, every order you process, and every growth initiative you launch will be shaped by the platform you choose.

A poor platform fit can lead to:

Limited growth potential: If your platform can’t handle higher traffic or more products, you’ll outgrow it quickly, leading to another costly migration down the line.

Frustrating customer experiences: Slow load times, clunky navigation, or complicated checkouts can cause shoppers to abandon their carts.

Operational headaches: Without the right features or integrations, your team may spend more time manually managing orders or fixing tech issues than growing the business.

Hidden costs: The wrong platform might seem cheaper upfront, but keeping things running smoothly could require expensive plugins, development work, or ongoing fixes.

On the other hand, the right platform acts as a growth partner. It evolves with your business, simplifies your workflows, and helps turn visitors into loyal customers.

Think of it like choosing a vehicle for a long road trip. You wouldn’t pick a small hatchback if you plan to drive across the country with the whole family and luggage. You’d want a reliable, comfortable car with enough room to grow into.

Your platform choice works the same way: Short-term fit + long-term vision = smart migration.

By taking the time to assess your options properly, you’ll be setting yourself up for smoother operations, happier customers, and easier scaling in the future.

Factors to Consider When Choosing a Platform

There’s no one-size-fits-all eCommerce platform. What works for a dropshipping startup may not suit a global DTC brand with complex inventory and international markets. That’s why choosing a platform requires a close look at your current operations and future goals.

Let’s break down the key factors you should evaluate when choosing a platform for migration:

1. Scalability

Your business will grow, so make sure your platform can keep up. Scalability isn’t just about handling more traffic; it’s also about supporting:

▪️ Product line expansion
▪️ Multi-store or multi-language setups
▪️ Cross-border commerce and tax rules
▪️ Advanced automation and integrations

A scalable platform ensures you won’t need another migration in two years because you have outgrown the system.

Ask yourself: Can this platform support our business 2–3 years from now without major rework?

2. Built-in Features vs. Customization Needs

Some platforms come packed with features out of the box. Others act more like blank canvases, giving you flexibility at the cost of more setup and dev work.

Feature-rich platforms like Shopify or BigCommerce are great for brands that want fast, functional stores with minimal development.

Highly customizable platforms like Magento or headless setups are better for businesses that require tailored workflows, custom checkout flows, or unique front-end experiences.

Tip: Map out the exact features you need now and in the near future. Then, evaluate which platforms natively meet 80–90% of them.

3. Integration Capabilities

No platform operates in isolation. Your store likely relies on tools like:

▪️ CRM (Customer Relationship Management)
▪️ ERP (Enterprise Resource Planning)
▪️ Marketing automation tools
▪️ Shipping and fulfillment systems
▪️ Payment gateways

Ensure your new platform complements your existing tech stack or allows easy integration with it via APIs, plugins, or third-party apps.

Pro Tip: The more native integrations available, the less you’ll spend on custom development and maintenance.

4. User Experience (For Both Customers and Your Team)

For your customers: Is the platform optimized for speed, mobile responsiveness, and smooth navigation? These directly impact conversion rates and SEO.

For your team: Is the admin panel intuitive? How easy is managing products, tracking inventory, processing orders, and running campaigns?

Bottom line: A platform should empower your team, not frustrate them.

5. Total Cost of Ownership (TCO)

Platform costs go far beyond monthly subscription fees. These include:

▪️ Development or setup costs
▪️ Theme or template expenses
▪️ Third-party app/plugin costs
▪️ Hosting and security (for self-hosted platforms)
▪️ Transaction fees and payment processing charges
▪️ Ongoing maintenance and support

Think long-term: A slightly more expensive platform might be cheaper overall if it saves time, reduces tech debt, and increases conversions.

6. Support & Community Ecosystem

When things go wrong (and they will), how quickly can you get help?

▪️ Does the platform offer 24/7 support?
▪️ Is there a developer community or agency network?
▪️ Are updates and security patches regularly maintained?

A strong ecosystem means faster problem-solving, better tools, and constant innovation.

7. SEO and Performance Capabilities

Search engines still drive a huge chunk of traffic. Make sure the platform supports:

▪️ Customizable meta titles and URLs
▪️ Fast page load speeds
▪️ Mobile optimization
▪️ Structured data support

These directly influence your site’s organic reach and user retention.

8. Future-Readiness

The eCommerce domain is evolving fast, with AI, personalization, headless commerce, and voice shopping shaping the future. Choose a platform that stays ahead of trends and doesn’t lock you into outdated technology.

Forward-thinking platforms support modular architecture, API-first frameworks, and third-party integrations to adapt easily.

3. Audit Your Current Website

Before you get into the technicalities of platform migration, take a step back and evaluate what you’re working with. Auditing your current website is a critical foundation that ensures your new store doesn’t carry over outdated data, broken pages, or missed opportunities. 

By thoroughly assessing your existing site’s structure, content, and performance, you’ll gain clarity on what to migrate, what to improve, and what to leave behind. Think of it as spring cleaning before the big move, organized, intentional, and geared for growth.

Here’s how to do it right:

1. Product Listings

Check for completeness: Ensure product titles, descriptions, pricing, images, variants, SKUs, and tags are accurate and consistently formatted.

Analyze performance: Use analytics to identify high-performing vs. underperforming products. Flag low performers for content updates or possible removal.

Evaluate metadata: Review SEO elements like meta titles, descriptions, and alt text on images for future SEO continuity.

2. Customer Database

Segment and clean: Review your customer data for outdated, duplicate, or inactive accounts. Segment by behavior, location, LTV, etc., to prioritize during migration.

Export securely: Make sure all data (names, emails, addresses, preferences, purchase history) is export-ready and compliant with data protection regulations (e.g., GDPR, CCPA).

Plan for re-engagement: Tag your most loyal customers for special reactivation campaigns post-migration.

3. Order History

Map historical data: Ensure historical order records are intact. This includes transaction IDs, dates, product details, statuses, and payment/shipping information.

Prioritize recent orders: These are crucial for handling active returns, exchanges, or support tickets.

Preserve continuity: Customers should be able to see their past orders even after migration. This builds trust and consistency.

4. Content Pages & Blog Posts

Inventory all pages: List all existing blogs, help center articles, landing pages, policy pages, etc.

Audit for relevance: Remove outdated content or merge thin pages into more comprehensive resources.

Retain SEO value: Identify top-performing content via Google Analytics/Search Console and plan redirects to preserve rankings.

5. Site Structure & URL Hierarchy

Document current URL structure: Capture all URLs, especially high-traffic and indexed pages.

Identify duplicate or broken links: Clean up any issues to avoid carrying them to the new platform.

Plan URL mapping & redirects: Ensure a 301 redirect plan is ready to maintain SEO equity and avoid traffic drops post-migration.

Helpful Tip: Use tools like Screaming Frog, Google Analytics, Google Search Console, or SEMrush to give your audit actionable insights.

4. Back Up Your Existing Data

Even the most well-planned migrations may involve risk and data loss, which can be devastating. Before making any changes, ensure you have a secure, comprehensive backup of your entire store. 

This is your safety net. If anything goes wrong during the transfer, you’ll have the confidence and capability to recover quickly without significant disruptions to your business.

Here’s what your backup should include:

1. Product Data

What to save: Titles, descriptions, SKUs, prices, inventory counts, categories, attributes, variants, tags, and related metadata.

Why it matters: Losing product details can delay your store’s relaunch, confuse customers, and affect SEO rankings.

2. Customer Information

What to save: Names, emails, shipping/billing addresses, contact preferences, account status, loyalty points, and saved carts.

Why it matters: This data powers your retention strategies. It’s also key for personalizing marketing and support after the migration.

3. Order Records

What to save: Order IDs, customer details, purchased items, dates, payment/shipping status, taxes, and refunds.

Why it matters: Order history builds customer trust and supports ongoing transactions, return requests, and analytics.

4. Website Files

What to save: All theme files, code customizations, page templates, navigation menus, scripts, and backend settings.

Why it matters: If your current site has custom logic or frontend design elements, you should preserve them for reference or reuse.

5. Media Files

What to save: All product images, banners, logos, video files, PDFs (manuals, guides), and any downloadable assets.

Why it matters: Media files often aren’t stored in the same database as other data. Without a proper backup, re-adding them manually can be time-consuming and error-prone.

With a secure backup in place, you can move forward confidently knowing your store’s data is protected, no matter what happens during the migration process.

Helpful Tip: Use both manual and automated tools for backup. Store copies securely in the cloud and offline (e.g., Google Drive + external hard drive) to ensure redundancy.

5. Map Data and Plan Website Structure

Once your data is backed up, the next critical step is to map out where everything will live in your new eCommerce platform. Think of this as your migration blueprint, ensuring your store’s structure, content, and customer experience remain seamless (or even improved) post-move.

Without a clear data mapping strategy, you risk mismatched product attributes, broken navigation, or a disjointed customer experience. Precision here protects your data integrity and supports a smoother transition.

1. Map Data Fields Between Platforms

Every eCommerce platform structures data a bit differently. To ensure a clean import:

Align product attributes:

▪️ Old: “Color” as a text field
▪️ New: “Color” as a dropdown with predefined options
→ Decide how to convert formats where needed.

Category hierarchy:

▪️ Old: “Men > Shoes > Formal”
▪️ New: “Footwear > Men > Formal Shoes”
→ Reorganize categories for better UX or SEO.

Customer data fields:

▪️ Old: Separate fields for “First Name” and “Last Name”
▪️ New: A unified “Full Name” field
→ Plan how to split or merge data accordingly.

Order details:

Ensure order status, payment info, and timestamps are supported in the new system’s format.

2. Plan Your New Website Structure

This is your chance to rethink and refine your site layout, not just replicate the old one.

Navigation menus: Will you keep the same structure or simplify categories?
Page hierarchy: Are you introducing new landing pages or consolidating existing ones?
Content strategy: Decide which blogs, FAQs, or support articles need updates, rewrites, or removal.

3. URL Structure Planning

Retain or change URLs?

▪️ Keeping the same structure simplifies SEO preservation.
▪️ Changing URLs? Prepare a 301 redirect plan to maintain rankings and avoid broken links.

Use a crawler tool (like Screaming Frog) to export current URLs and map them to their future counterparts.

With a mapped data plan and refined site structure, your migration becomes a controlled, strategic upgrade, not a chaotic overhaul.

Helpful Tip: Involve your SEO and dev teams early in the mapping process. This prevents costly technical debt and search traffic loss later on.

6. Plan the New Website’s Design and Theme

A platform migration is the perfect opportunity to rethink your store’s design, branding, and user experience. Whether you’re aiming for a subtle refresh or a full-scale makeover, your store’s visual identity should align with your business goals, customer expectations, and modern eCommerce best practices.

Think of this as your chance to not just move house, but to redecorate and optimize the layout while you’re at it.

1. Choose Your Design Approach

You have two primary options when it comes to design during migration:

Option 1: Retain Your Current Design

▪️ Ideal if you want to maintain brand familiarity and minimize disruption.
▪️ Best for stores where the current layout performs well and the user experience is already optimized.
▪️ May require slight adjustments to ensure compatibility with the new platform’s theme system.

Option 2: Go for a Complete Redesign

▪️ Great for brands looking to modernize, reposition, or address UX issues.
▪️ Offers the chance to improve navigation, product discovery, visual hierarchy, and overall aesthetics.
▪️ Consider revisiting design elements such as color schemes, typography, iconography, and interactive elements.

2. Prioritize Mobile Optimization

With mobile commerce accounting for over 60% of online sales, mobile-first design is no longer optional but essential.

▪️ Ensure responsive layouts that adapt to various screen sizes.
▪️ Simplify navigation and CTA buttons for easy mobile use.
▪️ Optimize image loading and performance for mobile connections.

3. Focus on Accessibility

Design should be inclusive and usable for everyone, including users with disabilities.

▪️ Use high-contrast color combinations.
▪️ Ensure font sizes and spacing support readability.
▪️ Add alt text to all images and ensure keyboard navigation support.
▪️ Make sure your theme meets WCAG 2.1 standards.

4. Don’t Forget Performance

▪️ Aesthetic upgrades shouldn’t come at the cost of site speed.
▪️ Optimize assets like fonts, scripts, and media to keep load times fast.
▪️ Test your new theme using tools like Google PageSpeed Insights or GTmetrix before launch.

A well-planned design strategy enhances user trust, encourages engagement, and supports higher conversion rates, making your new site not just functional but future-ready.

Helpful Tip: Involve your design and CRO teams during the redesign process. Beautiful design means nothing if it doesn’t convert.

7. Set Up Redirects (301s)

One of the most critical yet often overlooked steps in a platform migration is setting up 301 redirects. Without them, any URLs that change during the migration could result in broken links, 404 errors, and a steep drop in search engine rankings and referral traffic.

A well-executed redirect strategy ensures a seamless transition for users and search engines, preserving your hard-earned SEO value and user experience post-launch.

1. Why 301 Redirects Matter

User Experience: Visitors clicking on old links (from search results, emails, social posts, or bookmarks) should be automatically taken to the new equivalent page, without interruption.

SEO Preservation: Search engines treat 301s as a signal to transfer most of the link equity (ranking power) from the old URL to the new one.

Avoiding Traffic Loss: Pages that previously ranked well may lose visibility if they’re not properly redirected.

2. How to Build a Redirect Strategy

Export Your Current URLs

Use tools like Screaming Frog, Google Search Console, or your CMS backend to generate a full list of current URLs.

Map Old URLs to New URLs

▪️ Create a spreadsheet to pair every old URL with its new equivalent.
▪️ Try to maintain a one-to-one match wherever possible for clean redirection.

Handle Deleted or Consolidated Pages

▪️ Redirect removed pages to the most relevant category, product, or landing page, not just the homepage.
▪️ Avoid “soft 404s” by ensuring each redirect leads to a page that provides value.

Implement Server-Side Redirects

▪️ Set up 301 redirects at the server or CMS level.
▪️ Avoid JavaScript or meta-refresh redirects, as these don’t pass SEO value effectively.

3. Test Redirects Before Going Live

▪️ Use redirect testing tools like httpstatus.io or browser plugins to confirm proper implementation.
▪️ Check for redirect chains (A → B → C) or loops, which can harm load speed and crawlability.

4. Maintain a Redirect Log

▪️ Keep a backup of your redirect map for future reference or audits.
▪️ Monitor 404 logs post-launch to catch any missed or mistyped URLs and update your redirect rules accordingly.

A robust 301 redirect plan safeguards your SEO equity and ensures that loyal visitors, Google crawlers, and third-party backlinks all land on the right pages after the migration.

Helpful Tip: If you’re changing domain names as part of your migration, the 301 redirect strategy becomes even more critical. Apply redirects from old domain URLs to the new domain’s corresponding pages.

8. Integrate Third-Party Tools

A successful eCommerce platform migration isn’t complete without reintegrating your essential third-party tools. These integrations power everything from payment processing to customer engagement, and any hiccup in their setup can directly affect your operations, reporting, or customer experience.

Once your new site structure is in place, make a checklist of all the external tools your store relies on, and reconfigure them to ensure full functionality on the new platform.

1. Payment Gateways

Examples: PayPal, Stripe, Razorpay

Checklist:

▪️ Reconnect your merchant accounts.
▪️ Test sandbox and live transactions to verify successful order capture.
▪️ Confirm refund and dispute processes are functional.
▪️ Ensure currency settings, taxes, and payment methods are carried over correctly.

Why it matters: Payment issues = lost sales. Even a short downtime can frustrate customers and hurt credibility.

2. CRM & Email Marketing Tools

Examples: Klaviyo, HubSpot, Mailchimp, Salesforce

Checklist:

▪️ Reconnect contact forms, abandoned cart flows, welcome series, and transactional emails.
▪️ Map customer properties from your new platform to your CRM fields.
▪️ Retest segmentation, syncing, and automated workflows.
▪️ Verify that opt-in/opt-out preferences are preserved and compliant.

Why it matters: These tools are essential for lead nurturing, retention, and personalized experiences.

3. Analytics & User Behavior Tracking

Examples: Google Analytics 4 (GA4), Hotjar, Microsoft Clarity, Facebook Pixel

Checklist:

▪️ Add all relevant tracking codes and ensure they fire correctly across your new site.
▪️ Set up GA4 ecommerce tracking (purchases, cart events, product views, etc.).
▪️ Reconnect Google Tag Manager (GTM) containers if used.
▪️ Verify heatmaps and session recordings are functional on the new domain/structure.

Why it matters: Without accurate data, it’s impossible to measure the success of your migration or optimize going forward.

4. Shipping & Fulfillment Services

Examples: ShipStation, EasyPost, FedEx, UPS, DHL integrations

Checklist:

▪️ Reconfigure shipping rate calculators and label generation.
▪️ Re-link tracking updates and notification systems.
▪️ Confirm that shipping rules, zones, and carrier preferences are correctly migrated.

Why it matters: Smooth fulfillment keeps customers happy and prevents post-purchase complaints.

5. Other Possible Integrations

▪️ Loyalty and rewards systems
▪️ Reviews and UGC platforms (e.g., Clutch, Trustpilot)
▪️ Subscription billing tools (e.g., Recharge, Bold Subscriptions)
▪️ Live chat or support tools (e.g., Zendesk, Gorgias, Tidio)
▪️ Marketplace sync tools (e.g., ChannelAdvisor, CedCommerce)

When your third-party tools are reconnected and tested thoroughly, your store can function at full power from day one, supporting smooth operations, meaningful data collection, and engaging customer experiences.

Helpful Tip: Run a soft launch or test phase to validate every integration in a real-world checkout flow before going live. Use a staging environment to troubleshoot in isolation.

9. Test Extensively

Extensive testing is non-negotiable before you go live with your newly migrated eCommerce site. Even minor glitches like a broken checkout button or slow-loading product page can result in lost revenue, damaged trust, and frustrated users.

Think of this phase as your pre-launch rehearsal. You aim to simulate real-world usage across devices, browsers, and user journeys to catch and fix issues before your customers find them.

1. Functional Testing

What to check:

▪️ All navigation menus, product filters, category links
▪️ Buttons: Add to cart, wishlist, buy now, share, etc.
▪️ Forms: Contact forms, newsletter signups, account creation, search bar

Why it matters: One broken link or unresponsive button can create friction that leads to bounce or abandonment.

2. Mobile Responsiveness

Test across devices and viewports (mobile, tablet, desktop).

Check for:

▪️ Proper image scaling and text wrapping
▪️ Easy tap targets (buttons and links)
▪️ Mobile-friendly navigation (burger menus, dropdowns)

Use tools like: BrowserStack, Chrome DevTools, Responsively App

Why it matters: Most of your traffic likely comes from mobile, and poor responsiveness can tank conversion rates.

3. Checkout Process

Simulate real transactions:

▪️ Add different types of products to the cart
▪️ Apply discount codes, calculate shipping
▪️ Complete payment with different gateways (PayPal, credit card, etc.)

Check for:

▪️ Cart updates, tax calculation, order confirmation emails
▪️ Guest checkout vs. logged-in user experience

Why it matters: Nothing else matters if customers can’t check out smoothly.

4. Site Speed & Performance

Use tools like: Google PageSpeed Insights, GTmetrix, WebPageTest

Focus on:

▪️ Load times for home, category, product, and checkout pages
▪️ Identifying unoptimized assets (large images, unnecessary scripts)
▪️ Core Web Vitals: LCP (Largest Contentful Paint), FID, CLS

Why it matters: Faster websites improve user experience and positively impact SEO and conversion rates.

5. Additional Areas to Test

▪️ Browser compatibility: Test on Chrome, Safari, Firefox, Edge, etc.
▪️ Third-party integrations: Confirm all external tools (analytics, CRM, payment, shipping) are functioning.
▪️ 404 error handling: Check that non-existent URLs serve a branded and helpful 404 page.
▪️ Redirects: Verify your 301 redirects are working properly.

Thorough testing ensures your store goes live with confidence, minimizing surprises, maximizing performance, and delivering a polished, frustration-free experience from day one.

Helpful Tip: Create detailed test scenarios or checklists and assign team members specific areas to test. Also consider running a closed beta or soft launch for real-user feedback before public launch.

10. Do a Soft Launch

You’ve migrated your store, tested thoroughly, and are almost ready to go live. But, before opening the digital doors to everyone, it’s smart to do a soft launch. Think of this as a controlled dress rehearsal where you can catch last-minute issues in a real-world setting, with a limited audience.

A soft launch reduces the risk of surprises post-launch and allows your team to gather valuable feedback and refine while pressure is still low.

1. Who Should Be Included in the Soft Launch?

Internal teams: Let your marketing, sales, and customer support teams explore the new site. They’ll often spot inconsistencies or functionality gaps from a business perspective.

Key stakeholders: Share the experience with leadership, brand managers, and other decision-makers to align expectations and gather strategic input.

Loyal customers or power users: Offering exclusive early access to your VIP customers strengthens relationships and delivers honest, experience-based feedback.

2. What to Monitor During a Soft Launch

User Behavior: Use heatmaps, session recordings, and analytics tools (e.g., Hotjar, GA4) to track how users interact with the site. Are they navigating as expected? Are they dropping off at certain points?

Design & UX feedback: Are the layout, visuals, and navigation intuitive? Are any elements distracting or confusing?

Functional bugs: Look for issues that may have slipped through testing, like broken links, cart errors, display issues, or unexpected behavior on mobile or tablet.

Performance: Monitor loading times and responsiveness under light but real usage conditions.

Customer Support Load: Gauge if there’s a spike in queries or complaints, and identify common pain points that need addressing.

3. Gather and Act on Feedback

▪️ Use feedback forms, surveys, or direct outreach to collect input.
▪️ Tag and categorize issues (critical, nice-to-have, cosmetic).
▪️ Set a timeline for resolving bugs or making design adjustments before the full launch.

A soft launch helps you validate your migrated site in a low-stakes environment. You ensure a more confident, polished public launch and a better first impression by catching last-minute issues and optimizing based on real-user feedback.

Helpful Tip: Set expectations with a soft launch. Make it clear this is a test environment, and ask them to report anything unusual. You can even incentivize feedback with early access perks or small discounts.

11. Go Live & Monitor Post-launch Performance

It’s go time! After weeks (or months) of planning, auditing, designing, testing, and refining, your new eCommerce site is finally live. But launch day is just the beginning. What you do in the first few days and weeks after going live can make or break the success of your migration.

Post-launch monitoring is crucial to ensure everything works as expected in the real world and that your new site is performing against key business metrics.

1. Monitor Site Performance in Real Time

Traffic & behavior:

▪️ Use Google Analytics 4 (GA4) to monitor sessions, bounce rates, time on page, and conversion events.
▪️ Watch for sudden drops or spikes. These can signal success or technical issues.

Crawl errors:

▪️ Connect your site to Google Search Console and check regularly for crawl issues, broken links, or indexing problems.
▪️ Submit updated sitemaps and monitor how Google is interpreting your new URLs.

User experience issues:

Stay alert for broken images, missing content, layout issues, or cart errors, especially in browsers or devices you didn’t test as heavily.

2. Keep a Close Eye on SEO

Rankings: Track your top-performing keywords and pages from the old site. Watch for drops in search positions, and investigate causes.

Redirect effectiveness: Ensure your 301 redirects are doing their job. Use GSC or tools like Screaming Frog to verify.

Indexation: Monitor how quickly and accurately your new pages are being indexed. Look for duplicate content or canonical issues.

3. Track Key Business KPIs

Reference the goals and benchmarks you defined during your planning phase (e.g., from Step 1 of the migration process).

Common post-launch KPIs:

▪️ Conversion Rate
▪️ Revenue per Session
▪️ Cart Abandonment Rate
▪️ Average Order Value (AOV)
▪️ Page Load Speed

Why it matters: These metrics tell you whether the migration has had a positive or negative impact on your business.

4. Be Ready to Respond

Fix issues quickly: Any bug reports, 404s, or user complaints should be addressed immediately.

Communicate with your audience: If you’re experiencing known issues, let customers know transparently and set expectations.

Monitor support volume: If support tickets spike after launch, it may point to usability or technical issues that require further refinement.

A successful launch isn’t just about going live. It’s about staying sharp, responsive, and data-driven in the critical post-launch window. This ensures your migration delivers long-term performance gains, not just a short-term site update.

Helpful Tip: Set aside dedicated bandwidth for post-launch support. Assign team members to monitor analytics dashboards, customer feedback, and support channels daily for the first 1–2 weeks.
