An upgrade needs a compatibility check, a tested release and a recovery path. Which changes deserve particular attention before the new version reaches production?

Check runtime support windows, AMI changes and service compatibility notices. Roll out immutable application versions gradually and watch error rates. Database engine upgrades and infrastructure replacements need their own backup and rollback plans; an application rollback cannot undo every state change.
