Hi, I have the responsibility of looking after a Cisco DNA / Cisco Catalyst Center box, there is an update, can you tell me if it possible to rollback to the current version if the upgrade fails ?

Installed version:2.3.5.6-70143 - Release 2.3.7.6-70319 is available.

thanks in advance.

- If the upgrade fails , usually there will be an automatic rollback and cleanup (where needed) ,

No, there is no rollback feature. The portions that got upgraded will remain upgraded and the system will remain in a flux state until the upgrade is completed.

If you come across an upgrade that fails and the system is not recoverable or you just desire to go back to a previous version, the only option would be to reimage the cluster and restore from a backup.
