说明
Is it possible to downgrade or rollback a TPAM appliance to a previously installed version?
Is it possible to remove or uninstall a hotfix or upgrade patch?

解决办法
No, there is no uninstall concept in TPAM - it is not possible to remove hotfix or upgrade patches. TPAM has a revert to snapshot feature, however this is not guaranteed to be successful. It’s even possible over the course of normal operation that an appliance may lose its default snapshot
In order to remove a specific patch, the TPAM appliance would need to be set back to factory defaults, and a backup restored.
e.g.
1: Prior to installing patch, take a backup of the systemAfter the upgrade has been performed:
2: Revert the system to a prior snapshot

3: If the appliance was restored to a "Appliance Factory Defaults" snapshot, the appliance would need to have the initial configuration redone.

Note: The snapshots are generated automatically. More information in the below KB:

4: Restore the backup
Backups can only be restored at the same version. I.e. A backup taken at 2.5.915 can only be restored to 2.5.915.
Note: Once the 2.5.920 version has been applied, you will not be able to revert to an earlier version of TPAM. TPAM 2.5.920 is a major patch that makes significant changes to the OS and cannot be reverted.
