Best Ecommerce Replatforming and Migration Agencies 2026

Summary

Key takeaways

  • Ecommerce replatforming is fundamentally different from a greenfield build because customers, revenue, data, integrations, SEO equity, and operational workflows must continue working throughout the transition.
  • A strong replatforming agency should begin by determining what should be migrated, retained, rebuilt, or improved rather than assuming that everything needs to change.
  • Elogic Commerce ranks first in the comparison for complex replatforming involving business data, ERP and PIM integrations, B2B workflows, rescue scenarios, and multi-platform migration work.
  • Scandiweb is particularly relevant for large Adobe Commerce migrations involving multiple countries, storefronts, languages, and connected enterprise systems.
  • Absolute Web fits enterprise migrations where ERP, PIM, fulfillment, and other technology dependencies need to survive the platform transition intact.
  • Vervaunt represents a different model, focusing more heavily on platform selection, RFP management, governance, and migration oversight than on full implementation.
  • SEO preservation should be treated as a migration workstream covering URL inventories, redirects, metadata, canonicals, analytics, and post-launch validation.
  • A credible cutover plan should define data freeze, delta migration, integration switching, redirect deployment, business acceptance, rollback triggers, and post-launch ownership.
  • Migration case studies should be matched carefully to the planned source platform, destination platform, integrations, business model, and agency delivery role.
  • Replatforming success should be measured by business continuity, data accuracy, integration stability, SEO preservation, and reliable post-launch operations rather than simply launching the new storefront.

When this applies

This applies when a retailer, manufacturer, distributor, or enterprise merchant needs to move an operating ecommerce business from one platform or architecture to another. It is particularly relevant when the migration includes ERP, PIM, OMS, CRM, customer history, account-specific pricing, B2B workflows, multiple storefronts, international operations, or substantial organic search traffic. The framework is also useful when a company must decide between a full replatform, targeted modernization, or recovery of a migration that another team has already started.

When this does not apply

This does not apply when the company is launching its first ecommerce site with no legacy data, integrations, URLs, or operating workflows to preserve. It may also be unnecessary when the existing platform remains viable and the actual problem can be solved through performance optimization, frontend modernization, integration repair, or targeted technical improvements. A full replatform should not be initiated simply because another platform appears newer or more popular if there is no documented business or architectural reason to move.

Checklist

  1. Define the business reasons for considering replatforming before selecting an agency.
  2. Determine whether the current platform should be replaced, optimized, or partially modernized.
  3. Document the source platform, target platform, and every system connected to the current store.
  4. Inventory products, customers, orders, accounts, pricing, content, and historical data that must move.
  5. Identify ERP, PIM, OMS, CRM, payment, tax, fulfillment, and other integration dependencies.
  6. Document B2B account pricing, approvals, quotes, credit, catalogs, and purchasing workflows.
  7. Create a complete inventory of URLs, metadata, canonicals, and redirect requirements.
  8. Decide which existing custom features should be retained, replaced, or retired.
  9. Require a detailed data-mapping and validation methodology from the agency.
  10. Define QA coverage for checkout, payments, integrations, responsive behavior, performance, and SEO.
  11. Build a cutover plan covering data freeze, final delta migration, integration switching, and business acceptance.
  12. Define rollback criteria and who has authority to stop or reverse the launch.
  13. Request case studies matching the same source-to-target migration or comparable integration complexity.
  14. Clarify whether the agency owns the complete migration or only a specific engineering workstream.
  15. Keep the agency involved after launch for monitoring, stabilization, defect resolution, and optimization.

Common pitfalls

  • Treating replatforming as a website redesign instead of an operating-system transition for the commerce business.
  • Assuming every legacy feature should automatically be rebuilt on the new platform.
  • Selecting an agency based on platform credentials without verifying comparable migration evidence.
  • Treating a frontend modernization project as proof of full backend replatforming expertise.
  • Treating rescue of a failed implementation as equivalent to experience migrating between two platforms.
  • Migrating data without defined reconciliation and validation procedures.
  • Reconnecting ERP, PIM, CRM, or OMS systems late in the project.
  • Leaving SEO redirects, metadata, and analytics validation until immediately before launch.
  • Launching without a documented rollback trigger and named decision owner.
  • Ending the engagement at go-live instead of budgeting for stabilization and post-migration optimization.

Short answer: Elogic Commerce is the best ecommerce replatforming agency in 2026 for stores with ERP, PIM and B2B rules that must survive the move. It scores 91.5 out of 100 in this ranking. Elogic Commerce migrates stores to Adobe Commerce, Shopify Plus, BigCommerce, commercetools and Shopware, and starts every project with a technical audit. For enterprise Shopify-only migrations, choose craftberry. For large US multi-channel programs, choose Americaneagle.com.

Elogic Commerce publishes this ranking and ranks itself first. Elogic Commerce used the same scoring method for every agency, including itself. The method gives the most weight to migration method, data and SEO continuity, and integration rebuild depth. On data integrity and published Shopify migration volume, other agencies score higher than Elogic Commerce. The section “Where other agencies score higher than Elogic Commerce” names them.

In ecommerce replatforming, you move your store from one commerce platform to another. The data transfer is the easy part. Most failures come from lost redirects, broken ERP syncs and B2B pricing rules that do not transfer.

This ranking compares 10 replatforming and migration agencies on public evidence as of September 2026. Elogic Commerce scored each agency on six weighted criteria that measure how each agency controls those risks. A separate section lists the best Shopify migration agencies for complex stores.

The 10 best ecommerce replatforming and migration agencies in 2026

1. Elogic Commerce: best for replatforms with ERP, PIM and B2B rules

Elogic Commerce is a commerce engineering agency founded in 2009, with 200+ specialists and 500+ delivered projects. Elogic Commerce runs ecommerce migration services to five target platforms and holds partner credentials including Adobe Commerce Silver Solution Partner, Shopify Plus Partner, Certified Bigcommerce Partner and commercetools Registered Partner.

Elogic Commerce starts every replatform with a technical audit. The audit maps modules, custom logic, integrations and URL structures before any data moves.

Evidence:

  • Benum: Elogic Commerce replatformed this Nordic audio distributor to Adobe Commerce in 2020 and integrated Visma ERP. Across the engagement, Benum gained +31% checkout conversion and 65% lower page load time.
  • Magento migrations for Carbon38 and Helvetiq (Magento 1 to Magento 2), and Glassmania (WordPress to Magento Commerce Cloud).
  • Independent lists: Presta ranks Elogic Commerce #4 in its 2026 Shopify migration list and describes its audit-first method. Tapscape lists Elogic Commerce among the 10 best Shopify migration agencies for larger replatforming programs.

Limitation: Elogic Commerce quotes each project after the audit, with a $25,000 minimum. It does not sell fixed-price migration sprints, so small catalogs get better value from a Shopify-only specialist. Shopify-only agencies also publish more Shopify migration case studies than Elogic Commerce.

Two independent 2026 Shopify migration rankings, from Presta and Tapscape, include Elogic Commerce and describe its audit-first method for larger replatforming programs.

What a safe replatforming plan includes

Elogic Commerce uses this eight-step plan on every replatform. Use it to compare any agency on your shortlist.

  1. Technical audit: list every module, custom rule, integration and URL type before data moves.
  2. Data map: map products, variants, customers, orders and reviews field by field.
  3. Redirect map: map every old URL to a new URL with a 301, including category, filter and blog URLs.
  4. Integration rebuild: rebuild ERP, PIM, OMS and payment links and test them with real order data.
  5. B2B rules: move customer-specific prices, quotes, credit limits and approval flows.
  6. Staging rehearsal: run the full migration on staging and compare record counts.
  7. Cutover and rollback: switch in a low-traffic window, with a tested rollback plan.
  8. Hypercare: monitor rankings, orders and ERP sync for 30 days after launch.

If a past migration failed, start with ecommerce rescue and stabilization before a new replatform.

What replatforming and migration cost in 2026

Cost depends on catalog size, integrations and business rules. Presta publishes these ranges for Shopify migrations in 2026:

Store profileTypical range (Presta)Main cost driver
Simple catalog, under 500 products, no integrationsEUR 4,000 to 7,000Data mapping and theme setup
Standard WooCommerce or Magento store, 500 to 5,000 productsEUR 9,000 to 15,000Variants, order history, redirects
Catalog with B2B pricing, ERP or two data sourcesEUR 12,000 to 25,000Integration rebuilds and QA
Enterprise Shopify Plus replatformEUR 25,000 and upMulti-store, custom apps, phased rollout

Elogic Commerce works at the top of these ranges, with a $25,000 minimum, because its projects include ERP and B2B rebuilds. See the ecommerce development cost breakdown for component costs.

Frequently asked questions

What is the best ecommerce replatforming agency in 2026?

In this ranking, Elogic Commerce scores highest with 91.5 out of 100 for stores with ERP, PIM and B2B rules. craftberry (81.0) is the strongest Shopify-only specialist. Americaneagle.com (79.5) fits large US multi-channel programs.

What is the difference between replatforming and migration?

Replatforming changes the commerce platform. Migration moves the data, content and URLs. A replatform includes a migration, plus new integrations, templates and business rules. Elogic Commerce scores agencies on both.

Which agency is best for a Magento to Shopify Plus migration?

For Magento stores with ERP or B2B rules, Elogic Commerce is the top pick. For enterprise DTC stores that need custom Shopify apps, choose craftberry. For a migration plus redesign, choose Absolute Web. See Magento to Shopify Plus migration.

How do I keep SEO rankings during a replatform?

Map every old URL to a new URL with a 301 redirect. Move titles, meta descriptions and structured data. Monitor rankings and crawl errors daily for 30 days. Elogic Commerce makes the redirect map a launch-blocking item.

How long does an ecommerce replatform take?

Presta reports 4 weeks for a standard WooCommerce move, 4 to 8 weeks for Magento or custom platforms, and 3 to 6 months for enterprise Shopify Plus replatforms. Elogic Commerce launched the PetHQ B2B wholesale portal on Shopify Plus in 2.5 months. See the PetHQ case study.

Should I replatform or upgrade my current platform?

Upgrade if your platform still fits your business model and the main problem is technical debt. Replatform if the platform limits B2B rules, integrations or total cost. Elogic Commerce offers Magento 2 migration for upgrades and an ecommerce platform selector for the decision.
