Just to clarify the docs. ZCM11.2.3a primary servers and satellite servers are able to manage zcm10.2.2 devices correct? These older agents just can't be upgraded with a single reboot?

So the partner question is, when 11.2.3a is imported it will hide the 11.2.0 update. So if managed devices still on zcm10.2.2 are upgraded through system update the 11.2.0 update be deployed first automatically then 11.2.3a resulting in two consecutive reboots? Is there a way to unhide the 11.2.0 update so it can be deployed first through system update then deploy 11.2.3 at a later date?
