Fit
Who this is for
- Teams planning a Magento 2.4.9 or Adobe Commerce upgrade
- Stores with custom checkout, ERP/WMS sync, marketplace operations, or payment customisations
- Engineering leads who need a realistic QA and rollback plan before production changes
Signals
Warning signs
- Extension compatibility has not been checked against the target version
- Checkout, ERP, payment, or marketplace flows are not covered in upgrade QA
- Rollback ownership and decision criteria are unclear
Checklist
Practical checks to work through
Confirm current Magento version, PHP version, database version, and target upgrade path
Audit extension compatibility, abandoned modules, Composer constraints, and custom preferences/plugins
Test checkout, account, payment, shipping, tax, ERP, WMS, and marketplace order flows on staging
Validate theme compatibility, Hyva/frontend dependencies, and JavaScript bundle changes
Create a go-live checklist with maintenance window, database backup, cache steps, and rollback criteria
Record performance and error baselines before and after the upgrade
Target state
What good looks like
- Upgrade risk is known before the production window starts
- Critical customer and operations flows pass staging QA with documented evidence
- Rollback criteria are agreed before go-live, not during an incident
Watch-outs
Common risks
- Discovering extension conflicts during the live upgrade window
- Testing admin pages but missing checkout, ERP, and marketplace flows
- Treating successful deployment as success before post-go-live monitoring completes
Escalate
When to ask for senior help
- Your store has custom checkout, payment, ERP, WMS, or marketplace flows
- The upgrade touches multiple PHP, Composer, extension, and theme dependencies
- You need a senior review of QA scope and rollback readiness
