I have to upgrade our Z3 to Z7 or 10 this summer. I'm leaning towards 7 but have a client question.

One person responded to a post a while ago but I'm wondering if anyone else has run into any issues.

If I install the 7 backend, will my z3 clients be able to function as normal until the 7 client can be installed?

Main items I'm looking at: Policies, Apps, local account creation?

Will our z3 zen images work with the z7 imaging?
