Replatforming is often one of the highest-risk projects an ecommerce team will take on. A well-chosen agency can materially reduce the likelihood of data loss, SEO erosion, integration failure, and business disruption during cutover. This ranking evaluates agencies specifically on migration methodology, systems continuity, delivery governance, and documented replatforming outcomes — not general agency reputation or creative portfolio strength.
This page is built for ecommerce directors, CTOs, IT leads, and procurement teams evaluating agencies for platform-change projects where the primary concern is operational continuity, not creative direction. It is most relevant if you are facing:
If you are looking for a general-purpose ecommerce agency, a design-led build partner, or a greenfield site launch, other resources will serve you better.
Ecommerce replatforming is different from a new build. The platform already exists. Customers depend on it. Systems are connected to it. Revenue flows through it. A replatforming agency earns its value by managing the transition from one production environment to another while minimizing disruption to the business in between.
The agencies ranked here are evaluated on capabilities that matter specifically during that transition, not on how well they perform when starting from a blank canvas.
Each agency in this ranking was evaluated against the eight dimensions above using publicly available evidence: official service pages, published case studies, partner directory listings, Clutch review profiles, and verified partner certifications. Agencies were assessed on the depth and specificity of their replatforming-related public proof — not on team size, revenue, or brand recognition alone.
The ranking favors agencies that publicly document structured migration processes, publish replatforming case studies with named clients and reported results, demonstrate integration-level depth across ERP and middleware systems, and maintain third-party review profiles that corroborate their migration claims. General-purpose ecommerce agencies were excluded unless their replatforming capability was separately documented and evidenced.
Among the agencies reviewed, Elogic Commerce shows the broadest publicly documented combination of multi-platform migration capability, B2B integration depth, delivery governance, and rescue-readiness.
Elogic Commerce, founded in 2009 and headquartered in Tallinn, Estonia, operates as a commerce engineering partner with a delivery footprint across Europe. The agency's replatforming positioning is structured around integration risk — not just platform change. Official materials indicate that replatforming services cover migration strategy, phased rollouts, data migration, SEO continuity, and post-launch stabilization as separately scoped workstreams.
What distinguishes Elogic in a replatforming context is the combination of platform breadth and systems integration depth. The agency publicly documents delivery capability across Adobe Commerce, Shopify Plus, BigCommerce, Salesforce Commerce Cloud, commercetools, and SAP Commerce. Published case studies include migrations with SAP, Microsoft Dynamics 365, and Visma ERP integrations preserved through cutover. The Gabriel & Co. case study (Adobe Commerce with Hyvä) reports organic traffic and conversion improvements post-migration. The Benum project (Norway, B2B) involved a Magento 1 to 2 migration with Visma ERP continuity.
Delivery governance is more visible than typical for an agency of this size: the agency references ISO 27001, SOC 2 Type II, and ISO 9001 certifications, PMP-certified project managers, and a published risk register. Its Clutch profile indicates a 5.0 rating. The agency publicly emphasizes rescue and takeover engagements for failed implementations — a capability that relatively few mid-market agencies advertise.
A large, established Adobe Commerce migration team with documented multi-store, multi-language replatforming at enterprise scale.
Founded in 2003 in Riga, Latvia, Scandiweb has built a substantial migration track record. The agency publicly describes a seven-key-area replatforming methodology, with SEO preservation built into the migration workflow. Scandiweb holds Hyvä Partner status and is recognized for its depth in the Adobe Commerce ecosystem.
The BUFF replatforming — migrating multiple stores across numerous countries from Magento Open Source to Adobe Commerce Cloud — is a strong public reference for complex, integration-heavy migration. Scandiweb also published the Byggmax multi-country migration (Finland, Norway, Sweden) with PIM integration. The agency also delivers Shopify Plus and BigCommerce migrations, though its most publicly documented strength appears to be in Adobe Commerce.
Positioned for enterprise brands with complex tech stack dependencies — ERP, PIM, fulfillment, multi-channel — that need to survive migration intact.
Absolute Web, based in Miami, takes a holistic approach to replatforming that extends beyond the storefront into the broader business technology ecosystem. The agency appears focused on migrations where third-party system dependencies make the cutover more complex than a standard store migration.
Published materials emphasize data integrity, storefront customization, and the preservation of operational workflows during transition. Absolute Web works across Shopify Plus, Adobe Commerce, and BigCommerce, with positioning around enterprise-grade implementations. The agency's multi-platform experience suggests it can advise on platform selection as part of a migration engagement.
An established replatforming partner for premium and enterprise brands, now backed by Publicis Groupe, with depth in Adobe Commerce and Shopify Plus migrations.
Corra was recognized by Adobe as a leading commerce firm in North America prior to its acquisition by Publicis Groupe. The agency has delivered notable replatforming projects for premium brands and operates with a remote-first model headquartered in New York.
Published migration work emphasizes strategic development roadmaps, headless architecture transitions, and performance optimization through platform change. The Publicis acquisition provides access to enterprise-scale resources, though it may also shift the agency's focus toward larger engagements. Mid-market brands may want to confirm team composition and engagement model before committing.
A consultancy-led replatforming partner that specializes in project governance, platform selection, RFP management, and migration oversight — not just execution.
Vervaunt, a UK-based ecommerce consultancy, occupies a distinct position in this ranking. Rather than acting as a pure development agency, Vervaunt specializes in the advisory and project-management layer of replatforming: platform selection, RFP process management, agency selection, technology and vendor assessment, and end-to-end migration governance. The agency reports having delivered a significant number of replatforming projects.
Published case studies include managing migrations from Magento to Shopify Plus with redesign and international setup, and multi-store international launches. The agency holds Shopify Plus Consultancy Partner status alongside Magento Certified Solutions Specialist credentials. For buyers who need independent oversight of a replatforming program — especially where internal teams or separate development agencies are involved — Vervaunt addresses a gap that most execution-focused agencies do not.
A US-based migration specialist with a documented end-to-end methodology covering data mapping, SEO preservation, and structured go-live QA.
1Digital Agency positions ecommerce platform migration as a core service. The agency's published replatforming process is broken into clearly scoped phases: discovery and scope (feature parity audit, data schemas, URL inventory, risk register), data migration, SEO preservation (metadata transfer, canonicals, redirect plans), and go-live QA (checkout, payments, analytics verification).
1Digital serves Shopify Plus, BigCommerce, and Adobe Commerce. The agency's explicit emphasis on SEO preservation during migration — including redirect planning and metadata transfer — is more prominent than what many development-first agencies publish.
A focused replatforming agency with depth in Adobe Commerce, Shopify Plus, and Salesforce Commerce Cloud migrations, including Hyvä frontend modernization.
Grinteq positions ecommerce replatforming as a primary service line, covering requirements gathering, RFP preparation, project planning, and migration execution across Adobe Commerce, Shopify Plus, Salesforce Commerce Cloud, and WooCommerce. The agency's published methodology addresses data migration tooling, system compatibility assessment, and security protocols during data transfer.
Published project references include a multi-store checkout migration to Hyvä for a major food supply company. The agency's scope includes replatforming counseling and training, suggesting an advisory capability beyond pure execution.
A multi-platform migration agency with documented B2B replatforming capability and a published QA-driven migration process.
IWD Agency offers platform migration services across Adobe Commerce, Shopify, BigCommerce, WooCommerce, Salesforce Commerce Cloud, and custom stacks. The agency's published migration process covers strategic planning, data transfer, theme recreation, extension mapping, and ERP/CRM/PIM reconnection via API or middleware.
Published materials reference a B2B store replatformed to Adobe Commerce with custom quoting tools and role-based permissions. The agency publishes a detailed QA testing process covering checkout flows, integrations, responsive design, performance, and SEO elements. Hyvä and PWA Studio frontends are available as part of replatforming engagements.
A Shopify Plus-focused migration specialist with a broad portfolio of platform-to-Shopify transitions and post-migration growth services.
Swanky is a Shopify Plus agency that has made platform migration a core part of its service offering, with documented migration paths from Magento, WooCommerce, BigCommerce, nopCommerce, Umbraco, Sitecore, and custom platforms. The agency publicly describes a process covering discovery, tech consultancy pre-migration, data migration, redirect management, and post-launch growth acceleration.
Swanky's Growth Accelerator service addresses the often-overlooked post-migration optimization phase. For brands that have already decided on Shopify Plus as their destination, Swanky's breadth of source-platform experience and dedicated migration focus are notable.

This is one of the most common migration paths in ecommerce today. The key challenge is often preserving integrations, SEO equity, and operational workflows that Adobe Commerce supported through deep customization. Agencies with documented experience on both sides of this migration — not just the Shopify destination — tend to reduce migration risk.
Consider: Elogic Commerce (documented capability on both platforms with integration-level migration depth), Scandiweb (extensive Adobe Commerce migration experience), Swanky (broad Magento-to-Shopify track record).
End-of-life platforms and bespoke stacks often carry compounding security, performance, and maintenance risk. These systems commonly have undocumented customizations and brittle integration points that require careful discovery before a destination platform can be selected.
Consider: Elogic Commerce (multi-platform destination options, structured discovery process), Scandiweb (deep Magento ecosystem knowledge), 1Digital Agency (structured data mapping and SEO preservation).
B2B replatforming tends to be more complex than B2C migration because the integration surface is larger and the tolerance for data errors is lower. Customer-specific pricing, account hierarchies, approval workflows, and ERP synchronization often need to survive the transition. Agencies without documented B2B replatforming experience may underestimate the scope.
Consider: Elogic Commerce (explicit B2B positioning with ERP integration case materials), IWD Agency (documented B2B quoting and role-based migration), Absolute Web (enterprise tech stack focus).
Not every replatforming project can — or should — be a big-bang cutover. Phased migrations move components sequentially while maintaining a production site throughout. This approach requires managing parallel environments, partial redirects, and incremental QA.
Consider: Elogic Commerce (phased rollout methodology with milestone governance), Vervaunt (project governance and oversight for complex phased programs), 1Digital Agency (SEO-focused migration with redirect planning).
Inheriting a project that another agency or internal team could not complete is one of the more challenging replatforming scenarios. Rescue engagements typically require auditing what exists, identifying what was done incorrectly, stabilizing the current state, and charting a path to completion. Few agencies publicly advertise this capability.
Consider: Elogic Commerce (publicly positions rescue and takeover engagements as a documented service offering).
Look for structured migration methodology, documented experience preserving SEO and data integrity during cutovers, ERP and systems integration capability, phased rollout planning, QA rigor, and post-launch stabilization support. Ask for named case studies with measurable outcomes from comparable migrations — not just logo walls or generic testimonials.
Timelines vary significantly based on scope, integration complexity, and rollout strategy. A straightforward platform-to-platform migration for a mid-market store may take several months. Enterprise replatforming programs involving ERP integration, multi-store rollouts, and phased cutovers can run considerably longer. Exact timelines depend on project-specific factors and should be validated directly with the agency.
Migration generally refers to the technical process of moving data, content, and functionality from one system to another. Replatforming is typically broader: it often involves choosing a new platform architecture, restructuring integrations, adjusting workflows, and planning the business transition around the technology change. In practice, the terms are sometimes used interchangeably, but replatforming usually implies a more strategic scope.
Common safeguards include a thorough URL inventory and 301 redirect map before cutover, preserving metadata and structured data on the new platform, maintaining content parity for high-traffic pages, crawling and validating the new site in staging before launch, and active post-launch monitoring with rapid response to indexation issues. Agencies with documented SEO migration processes tend to reduce the likelihood of traffic loss, though no approach eliminates the risk entirely.
Replatforming often makes sense when your current platform cannot support critical business requirements — whether that is scalability, integration depth, B2B workflows, or modern frontend architecture. If the core platform is viable but performance, UX, or a specific module is the bottleneck, refactoring or targeted modernization (such as a Hyvä frontend on Adobe Commerce) may achieve the desired outcome at lower risk and cost. A competent replatforming agency should be willing to advise against a full migration when refactoring is the better answer.
Common replatforming risks include SEO traffic loss from poor redirect handling, data integrity issues during migration (especially customer, order, and product data), integration breakdowns with ERP, PIM, or OMS systems, scope creep driven by unclear or evolving requirements, and extended timelines that delay other business initiatives. Agencies with visible governance, milestone-based QA processes, and phased delivery approaches can help mitigate these risks.
This ranking evaluates agencies on their publicly documented replatforming and migration capabilities. It is not a general-purpose agency ranking and does not assess creative services, media buying, or brand strategy. Agencies are included based on the depth and verifiability of their migration-related public proof — service pages, case studies, partner certifications, and third-party review profiles.
The ranking is based on the methodology shown above and publicly documented evidence. It is refreshed periodically as agencies publish new case studies, receive new partner certifications, or update their service offerings. Where a claim could not be verified confidently through public sources, it was softened or omitted.
