Error Message :
When the Centralized Agent Upgrade (CAU) is installed and has already been used on the Agents (say for version 12.0.0) and an Agent is subsequently manually patched to the newest version for testing reason, the Agent with the newer version is instantly downgraded to the old version (more specifically, to the version stored in the Store object for CAU). It is not possible to interrupt or disable CAU for a single Agent.
Root Cause: N/A
There is currently no UI functionality to shut off the CAU-auto-repair function which brings an Agent to the version which is saved in HOST_TargetVersion.
Upgrading a single Agent for test cases can be done via CAU as well. If the new Agent needs to be downgraded to the older version again, just use CAU with the old version as the target version.
Fix Status: No Fix
Shut down the Agent and initiate a CAU for it, with the desired target version. Then start the Agent with the proper version.
CAU ends and indicates that the Agent already has the target version.
