After enabling ITCM agent auto upgrade via configuration policy, agents in the environment are still not upgrading.
Client Automation (ITCM) -- any version.
If none of the above suggestions resolves the problem with agent auto-upgrade, please open a support case.
In order to properly debug, DETAIL level traces will be required of the sd_server process:
cftrace -c set -l detail -s 50000 -ln 4 -f usd -pp sdserver
Once detail traces are set on the scalability server, run a caf register on an agent that is not auto-upgrading, and make a note of the agent name when uploading logs to the case.
