Migration to Adobe Commerce Cloud: complete guide 2026


Why migrate to Adobe Commerce Cloud in 2026?


Adobe Commerce Cloud (formerly Magento Commerce Cloud) is Adobe's managed hosting platform for high-growth e-commerce sites. In 2026, it is the obvious choice for businesses that want to combine performance, security, and scalability.


Key benefits


  • **Managed infrastructure**: Adobe manages the infrastructure, updates, and security
  • **Fastly CDN included**: optimal edge performance without complex configuration
  • **Multiple environments**: isolated development, staging, production
  • **Auto-scaling**: the cloud adapts to your traffic
  • **New Relic integrated**: monitoring and observability ready to use

The 5 migration phases


Phase 1: Audit and preparation


Before any migration, a complete audit is essential:


  • Inventory of installed modules and extensions

2. Analysis of current performance

3. Identification of technical blockers

4. Time and budget estimation


Phase 2: Cloud infrastructure configuration


Once your Adobe Commerce Cloud project is created:


  • Configure environments (Integration, Staging, Production)
  • Set up environment variables
  • Configure Fastly CDN
  • Set up New Relic
  • Define SSH access and roles

Phase 3: Data migration


Data migration is the most critical step:


  • Use the Migration Tool (data migration module)
  • Migrate settings first, then data, then deltas
  • Validate data integrity after each step
  • Test performance in staging environment

Phase 4: Code adaptation


Magento 2 code must be adapted for the Cloud:


  • Use the .magento.app.yaml file to configure your application
  • Define .magento/services.yaml for services (MySQL, Redis, Elasticsearch/OpenSearch)
  • Configure .magento/routes.yaml for routing rules
  • Adopt Cloud best practices (read-only files, logging to stderr)

Phase 5: Testing and go-live


Before switching to production:


  • Full functional tests

2. Performance tests (load, stress)

3. Security tests

4. Rollback plan

5. DNS migration and cutover


Pitfalls to avoid


  • **Incompatible extension**: verify Cloud compatibility of your modules
  • **Fastly configuration**: misconfiguration can break caching
  • **Indexing**: scheduled mode is mandatory on Cloud
  • **Storage**: watch disk space limits

Cost and return on investment


The cost of Adobe Commerce Cloud depends on your revenue and needs. Budget between €30,000 and €200,000 per year depending on the license. The investment is justified by:


  • Reduced infrastructure costs
  • Improved performance (better conversion rate)
  • Enhanced security (lower risk)
  • Availability (99.99% SLA)
