Do not update several critical components simultaneously in production. Prepare a current staging copy and verify that backups can be restored.
Before updating
- Review the changelog and version requirements.
- Back up the database, uploads, and custom code.
- Record the working versions.
Test on staging
Retest sign-in, search, cart, checkout, email, digital downloads, and cron tasks. Deploy only when no critical PHP or JavaScript errors remain.
Rollback plan
Keep the previous release package and a database-restoration procedure ready. If an issue appears, prefer a controlled rollback to an untested hotfix.
