I have just upgraded from ZCM 11.4.3 to ZCM 2017 on a ZCM 2017 appliance in a single primary server system. I see a number of system update folders under /var/opt/novell/zenworks/content-repo/sytem-update. Can I delete all of them except the most recent?

Is there a way to tell which subdir goes to a specific system update? I still have not baselined the ZCM 11.4.3 update because a couple MAC devices are not showing up as having gotten the 11.4.3 ZCM agent, even though when checking on the MAC itself, it shows the 11.4.3 agent so I want to keep this update.

Is there a safer way to do this other than manually going in and whacking the subdir?
