I have to upgrade from 10.2.2 to 10.3.0a. But there is a large workstation base with an foreign image and a 10.2.2 agent on them.
They all have to be reimaged anyway, but not for some month.

I'm planning to let them run on 10.2.2 after the 10.3.0a upgrade, and let the workstations with the "real" image update to the 10.3.0 agent.

Has anyone had experience running a lot of workstations with 10.2.2 agent against a 10.3 zone?
Did you have any problems?
