10 Best Shopify Migration Agencies in the USA 2026
Replatforming to Shopify or Shopify Plus in 2026 isn’t “move the data and flip the switch.”
For most DTC and retail brands, the wrong migration partner means lost SEO, broken tracking, angry customers, and months of firefighting while your team burns through budget and runway.
The right partner treats migration as a revenue-critical project, not just a dev task. Done well, a move from Magento, BigCommerce, WooCommerce, or a custom cart to Shopify should:
- Protect your organic traffic and rankings
- Keep products, customers, orders, and content intact
- Plug in your real tech stack (ERP, CRM, subscriptions, reviews, analytics) without drama
- Give shoppers a faster, cleaner, higher-converting storefront
Instead of wading through endless partner directories and Clutch profiles, this guide highlights 10 Shopify migration agencies in the USA we’d actually short-list for a serious B2C/DTC replatform.
Start here, then pick 2–3 to have real conversations with.
Commerceshop
CommerceShop (CommerceShop) is a Shopify migration and eCommerce development agency founded in 2009. It has delivered 500+ Shopify stores and completed 200+ successful migration projects for ecommerce brands across multiple industries.
The agency delivers Shopify and Shopify Plus migrations using a structured, risk-controlled replatforming process built to protect SEO equity, preserve critical store data, and execute a stable cutover.

Customer Review
“They’ve never turned down a challenge and resolved problems even the most seasoned developers have yet to encounter.”
|
Best for
- High-stakes Shopify and Shopify Plus migrations, where SEO and revenue must be protected
- Magento to Shopify migration replatforms with complex data and a long order history
- Brands that want migration plus Shopify development and customization, theme implementation, app, and third-party integrations.
- Stores with heavy ERP, CRM, subscription, reviews, and analytics integrations
- Teams that need SEO-safe migrations, structured QA, and Ongoing maintenance and support
Why It Stands Out
CommerceShop frames migration as an end-to-end process (not just data transfer), and promotes an AI-powered migration framework aimed at reducing downtime and preventing common SEO/data loss during replatforming.
eSEOspace
eSEOspace is a U.S.-based web design, development, and SEO agency that has launched 1,284+ websites across industries including e-commerce, healthcare, financial services, and technology. Voted #8 Best Website Designer in the World by DesignRush & Clutch, with 150+ five-star reviews, the agency delivers Shopify and Shopify Plus builds, migrations, and ongoing optimization backed by a team of 29 marketing and development professionals.
The agency’s Shopify migration process covers inventory and variant mapping, content migration, URL mapping with 301 redirects at scale, structured data and metadata preservation, and post-launch monitoring — all grounded in eSEOspace’s signature SEO-preservation methodology. Their background in Behavioral Neuroscience and Marketing Strategy drives a conversion-first approach to every store they build.

Customer Review
“Super happy with the services eSEOspace provided, especially by the fact that Irina ensured our vision was portrayed on our website. She worked with us for many hours each day on edits, and I never felt rushed — she treated us as if we were her biggest client even though we knew our budget was not very large.”
– Ben G., Project Manager, Waterfront Painting
|
Best for
- SEO-safe Shopify migrations where rankings and organic traffic must be preserved
- Brands that want a conversion-driven redesign alongside their platform move
- E-commerce stores needing CRM, ERP, subscription, and marketing-automation integrations
- Teams looking for ongoing maintenance, managed hosting, and premium support post-launch
- Industries with compliance needs (HIPAA, ADA/WCAG 2.1 AA, GDPR/CCPA)
Why It Stands Out
eSEOspace treats every Shopify migration as a combined SEO, UX, and revenue project — not just a data transfer. Their SEO-preservation framework, conversion-rate-optimization expertise, and structured post-launch support program mean brands don’t just move to Shopify; they launch a faster, higher-converting store without sacrificing the organic traffic they’ve already earned.
Expert Village Media
Expert Village Media is a Shopify development agency founded in 2011. With 14+ years in the ecommerce ecosystem and a portfolio of 2000+ Shopify projects spanning brands across 30+ countries, it operates as a Shopify Select Partner offering store design, custom development, migration, and digital marketing under one roof.
The agency delivers Shopify and Shopify Plus migration services from Magento, WooCommerce, BigCommerce, and custom or legacy carts, covering full data transfer (products, customers, orders, and content), theme design and customization, app and third-party integrations, and SEO-safe cutovers with redirect and metadata mapping. Migration work is paired with in-house SEO, CRO, and paid media, so brands can replatform and keep growing with the same team rather than handing off after launch.
|
Customer Review
“”We worked with Expert Village Media on our wholesale website rebranding and had a very positive experience. They understood our B2B needs, especially around customer registration, account approval, and controlled pricing visibility.” – Client review, Clutch”
|
Best for
- Shopify and Shopify Plus migrations from Magento, WooCommerce, BigCommerce, and custom carts
- B2B and wholesale replatforms involving account approval, customer registration, and controlled/tiered pricing
- Brands that want migration plus theme design, custom development, and app/integration work
- DTC and retail stores needing SEO-safe migration with redirect and metadata mapping
- Merchants who prefer one team across migration, SEO, CRO, and paid media
Why It Stands Out
Expert Village Media pairs replatforming with full-stack Shopify capability, including design, custom development, app integrations, and SEO. It emphasizes zero-downtime migrations backed by verifiable signals: a Shopify Select Partner listing, named case studies, and public client reviews on Clutch.
Ecomx Shopify Plus Agency
Ecomx Agency is a Shopify Plus design and development agency founded in 2015 and based in New York City. The agency works only on Shopify, handling new store builds, redesigns, and migrations for brands across fashion, beauty, jewelry, home, and food.
As a dedicated Shopify Migration Agency, Ecomx delivers migrations from WooCommerce, Magento, BigCommerce, and custom carts, covering full data transfer (products, customers, and orders), theme rebuilds, app integrations, and SEO-safe launches with redirect mapping. Migration is paired with in-house SEO, CRO, and support, so brands can replatform and keep growing with the same team.
|
Customer Review
“Migrating our WordPress site to Shopify Plus felt risky, but Ecomx made it easy. They handled the design, and we didn’t lose any rankings.”
– eCommerce Manager (WordPress to Shopify Plus migration) |
Best for
- Migrations from WooCommerce, Magento, BigCommerce, and custom carts
- Brands that want migration plus a theme rebuild or redesign
- DTC, retail, and B2B/wholesale stores
- Stores with app and third-party integrations
- Teams that want one partner across migration, SEO, and CRO
Why It Stands Out
Ecomx works on Shopify exclusively and treats migration as more than a data export, pairing SEO-safe launches with design, development, and CRO in one team.
ECORN Agency
ECORN is a Shopify-focused agency with 7 years in the Shopify ecosystem and 100+ completed projects, including 20+ platform migrations. Their team handles everything from data-heavy catalog migrations to full store redesigns, with a track record of keeping projects on tight timelines.
For migrations specifically, ECORN takes a business-continuity-first approach — mapping redirects, preserving SEO, and cleaning up data architecture before go-live, rather than treating it as a simple copy-paste. They’ve handled complex migrations including a 1M+ SKU catalog move from Magento to Shopify Plus for CoverKing.com, where they also built a custom PIM process around the new platform.
ECORN works with D2C, fashion, and lifestyle brands, and offers flexible retainer-based engagement (starting from 35 hrs/month) as well as fixed-scope migration projects.
|
Customer Review
“Guys really did a great job and helped us develop and migrate in less than a month!”
– Pavels, Vitrum.lv (Magento → Shopify migration)
|
Best for
- Brands migrating from Magento, WooCommerce, or other platforms to Shopify/Shopify Plus
- Stores with complex product catalogs or custom data structures
- Teams that need a dedicated Shopify partner long-term, not just a one-off job
Why It Stands Out
ECORN’s 20+ completed migrations combined with deep Shopify expertise means they handle edge cases that generic agencies struggle with: bulk product data, custom integrations, PIM setups, and zero-downtime cutover. The Vitrum migration shipped in under a month.

Why It Stands Out

How To Choose The Right Partner
The right migration partner should make your move to Shopify feel controlled, predictable, and commercially smart. Use this quick filter to shortlist agencies:
Match for your scenario
Check their “Best for” against your reality: current platform (Magento/BigCommerce/WooCommerce/custom), catalog size, DTC vs B2B, and revenue band.
Look for real migration proof
Prioritize named platform → Shopify case studies, not just “Shopify builds.” Ask for 1–2 recent replatforming references.
Lead with SEO + data, not just design
Ask:
How do you handle redirects and metadata?
Who owns data mapping and validation?
What’s your process the week of launch?
Clarify integrations and ownership
Put your stack on the table (ERP, CRM, subscriptions, WMS, reviews, analytics). Confirm which pieces they’ve handled before and who is responsible for what.
Lock scope, timeline, and support
Align on launch scope, timeline, change-control, and post-launch support (response times, what’s included, when the handoff ends).
Conclusion
Replatforming is one of the few moves that can reset your ecommerce trajectory in a single project. Get it right, and you keep your SEO, clean up years of tech debt, and give shoppers a faster, higher-converting store on Shopify or Shopify Plus.

FAQs about Shopify Migration
1. Do we really need a specialist agency for Shopify migration?
If you have real traffic, orders, and integrations, yes. Migration is a revenue and operations project, not just a data export. A specialist has a tested process for SEO, data, and launch, so you are not learning on production.
2. How long does a Shopify migration usually take?
Most serious migrations take 8 to 16 weeks. Timing depends on catalog size, design scope, integrations, and how quickly your team can review and approve.
3. How do we avoid losing SEO when we move to Shopify?
You need a clear SEO plan: URL and redirect mapping, metadata migration, handling removed URLs, and post-launch checks for 404s and indexing. SEO should be a core workstream from day one.
4. What data should be migrated to Shopify?
At minimum: products, collections, customers, orders, pages, blogs, and key SEO fields. Many brands also offer reviews, gift cards, store credit, and subscriptions. Create a data inventory and confirm how each item will be handled.
5. Can we keep our current design when migrating?
Yes. You can mirror your current design in a Shopify theme with small fixes, or use the move for a focused UX refresh. Many brands keep the core brand look and upgrade PDP, navigation, cart, and checkout.
6. What should we ask agencies on the first call?
Ask about a recent migration from your platform to Shopify, how they handle SEO and redirects, who owns data mapping, and which of your key integrations they have done before. Then ask what launch week looks like with their team.
