Adobe Commerce Migration Guide

Introduction

An Adobe Commerce migration is a business and operational transformation, not simply a transfer of code. Data, integrations, customer journeys, SEO and team readiness all require coordinated planning.

Discovery

Audit the current platform, extensions, customizations, integrations, data volume and SEO requirements. Identify obsolete functionality as well as capabilities that must be preserved or redesigned.

Migration Planning

Define scope, environments, data mappings, delivery stages, ownership and a realistic timeline. Establish rollback criteria and rehearse the rollback process before launch.

Data Migration

Plan repeatable migration for products, customers, orders, CMS content, URLs and media. Validate counts, relationships, identifiers and transformations after every rehearsal.

Custom Code Review

Assess extension compatibility, custom modules, deprecated APIs and theme architecture. Replace unsupported dependencies deliberately instead of carrying historical complexity into the new platform.

Integration Validation

Test ERP, payment, shipping, CRM and API integrations across success, failure and retry scenarios. Confirm security controls and operational ownership for every connection.

Performance and Security

Validate caching, indexing and infrastructure under representative workloads. Apply supported patches, review dependencies and establish vulnerability and update processes.

UAT and Launch

Cover regression testing, SEO redirects and metadata, checkout, payment, tax, fulfillment and complete order flows. Define launch checkpoints, communications and rollback readiness.

Post-Launch

Monitor errors, performance, integrations and commercial journeys during stabilization. Prioritize verified issues before beginning the next optimization phase.

Conclusion

A phased migration with repeatable rehearsals, measurable acceptance criteria and clear operational ownership reduces risk and creates a stronger foundation for future improvements.
