For UK and European enterprise brands, replatforming is no longer just about keeping the lights on, it’s also about opening the door for growth and better performance, while at the same time keeping up with customer expectations that are getting higher all the time. If you’re dealing with a legacy Magento build or a custom-built store, shifting over to Adobe Commerce, with the help of seasoned Adobe Commerce development services can unlock scalability, give you more room to maneuver, and bring enterprise-level capabilities you need to compete in today’s digital commerce scene.
This guide kind of walks you through the main things to consider, what steps usually come next, and which best practices to use when replatforming to Adobe Commerce, especially when you’re thinking about the reality of UK and European ecommerce teams.
Why Replatform to Adobe Commerce?
Adobe Commerce (formerly Magento Commerce) is this kind of powerful, flexible platform, built for those really complex B2B and B2C operations. It’s especially handy for enterprises that require, or sort of expect, a lot of customization and fine tuned control, and who also want to scale over time, without getting stuck.
- Advanced customisation without being locked into rigid SaaS templates
- Multi-store and multi-currency support for pan-European operations
- Deep ERP, PIM, and CRM integrations to support complex back-office workflows
- Robust B2B functionality, including company accounts, negotiated pricing, and quote management
With extended support for those older Magento versions that end around August 2026, a lot of UK merchants are kind of already looking at what to do, so they can avoid security and compliance headaches, because honestly that risk stuff stacks up. Replatforming now can help you take advantage of Adobe’s cloud native setup as well as better performance and continual improvements, like ongoing innovation that keeps moving.
Step 1: Define Your Business Goals and Requirements
Before you write a single line of code, clarify what success looks like. Common enterprise goals include:
- Increasing conversion rates and average order value
- Reducing total cost of ownership (TCO) compared to legacy systems
- Enabling faster time-to-market for new features and markets
- Improving site speed, reliability, and scalability during peak
Team up with the stakeholders across ecommerce, IT , marketing, and finance, to gather, like actually document the must-have capabilities, the integrations, and the compliance items needed (for example, GDPR and PSD2/SCA for payments across Europe). This discovery stage is kind of the base layer for your replatforming plan and it should guide the selection of digital commerce solutions plus the partners you end up working with.
Step 2: Choose the Right Adobe Commerce Architecture
Adobe Commerce offers several deployment models:
- Adobe Commerce on Cloud (SaaS/PaaS): Managed infrastructure with built-in scaling, security, and DevOps tooling. Ideal for teams that want to focus on commerce rather than server management.
- On-premises or private cloud: Greater control but higher operational overhead. Often chosen by highly regulated industries or those with specific data residency needs in the EU.
- Composable/headless setups: Use Adobe Commerce as the commerce engine while pairing it with best-of-breed front-end frameworks (e.g., Next.js, Nuxt) and services for search, content, and personalisation.
For most UK and European businesses, Adobe Commerce on Cloud kind of gives the best balance of performance, security and agility, particularly when they are expanding into more than one market.
Step 3: Select Your Implementation Partner
Replatforming is kind of a strategic investment not really a DIY project. The right partner will act like an extension of your team, bringing deep expertise in Adobe Commerce development services, and ecommerce website development services, too.
Look for agencies that:
- Have proven experience with enterprise Adobe Commerce migrations (especially from Magento 1/2 or SAP Hybris)
- Understand UK/EU compliance, VAT, and multi-currency complexities
- Offer end-to-end support: discovery, design, development, data migration, QA, launch, and post-go-live
Ask for case studies, client references, and a clear project methodology. A strong partner will help you avoid common pitfalls such as underestimating data migration complexity or neglecting SEO during the cutover.
Step 4: Plan Your Data Migration Carefully
Data migration is often the riskiest part of replatforming. You’ll need to move:
- Product catalogues (including attributes, categories, and media)
- Customer accounts and order history
- Pricing rules, promotions, and customer groups
- SEO metadata and URL structuresexperienceleague.
Best practices include:
- Auditing your current data: Clean up duplicates, obsolete SKUs, and inconsistent attributes before migration.
- Mapping fields meticulously: Ensure every source field has a clear destination in Adobe Commerce, and create custom fields where needed.
- Running test migrations: Validate data integrity in a staging environment before the final cutover.
- Preserving SEO equity: Crawl your existing site, export all indexed URLs, and prepare a comprehensive 301 redirect map to protect organic traffic.
For large catalogues or complex B2B pricing structures, consider phased migration by category or customer segment to reduce risk.
Step 5: Design for Performance and User Experience
A replatform is your chance to reset your user experience. Key priorities for UK and European shoppers include:
- Fast page load times: Aim for sub-2-second load times on mobile and desktop. Adobe Commerce’s cloud infrastructure, combined with modern front-end practices (e.g., Hyva themes), can deliver significant speed gains.
- Mobile-first design: Over 60% of UK ecommerce traffic comes from mobile devices. Ensure your new storefront is fully responsive and optimised for touch interactions.
- Localised experiences: Support multiple languages, currencies, and tax rules for seamless cross-border shopping across Europe.
- Accessible and compliant design: Meet WCAG 2.1 AA standards and ensure cookie consent, privacy policies, and payment flows comply with UK/EU regulations.
Invest in UX research and usability testing early to validate navigation, checkout flows, and product discovery before launch.
Step 6: Integrate with Your Enterprise Stack
Enterprise ecommerce doesn’t operate in isolation. Your Adobe Commerce platform will need to integrate with:
- ERP systems (e.g., SAP, Microsoft Dynamics) for inventory, pricing, and order management
- PIM solutions to manage rich product content across channels
- Payment gateways that support PSD2/SCA, local methods (e.g., iDEAL, Klarna, Sofort), and multi-currency settlements
- CRM and marketing automation tools for personalised campaigns and lifecycle
Design these integrations with resilience in mind: use async APIs, message queues, and idempotent syncs to handle failures gracefully under load. Document every integration point and establish clear ownership for monitoring and support post-launch.
Step 7: Test Rigorously Before Go-Live
Enterprise replatforming demands a disciplined testing approach. Your QA plan should cover:
- Functional testing: Verify all features, workflows, and integrations work as expected.
- Performance testing: Simulate peak traffic (e.g., Black Friday, Boxing Day) to ensure the platform scales.
- Security testing: Conduct vulnerability scans and penetration testing, especially for payment and customer data.
- User acceptance testing (UAT): Involve real business users to validate the platform against day-to-day operations.
Run at least one full dry-run cutover in a staging environment to rehearse the launch sequence, validate data, and confirm redirect maps. This reduces the risk of surprises on go-live day.
Step 8: Launch, Monitor, and Optimise
Go-live is not the end—it’s the beginning of a new growth phase. In the first 90 days:
- Monitor Search Console daily for crawl errors, redirect gaps, or indexing issues.
- Track core KPIs: Conversion rate, average order value, bounce rate, and page speed.
- Gather user feedback: Use surveys, session recordings, and heatmaps to identify friction points.
- Iterate quickly: Prioritise high-impact fixes and enhancements based on data and user insights.
Work with your partner to establish a roadmap for continuous improvement, whether that’s adding new markets, launching B2B portals, or experimenting with composable commerce architectures.
