Verification & Rollback
This section covers how you confirm patch jobs have succeeded and what to do when you need to undo a release.
Verification
After a patch job completes, confirm that hosts are healthy, the expected packages are installed, applications still pass checks, and vulnerability scans reflect the patched state.
Rollback Procedures
If a patch causes instability or fails verification, use this guide to learn how to roll back, how rollback scripts or snapshot restores fit into the process, and how to close the loop with follow-up actions.
