Hi

I know that there is no support for upgrading SCCM 2012 RTM to SCCM 2012 R2.  So, i need to apply SP1 first and perform than an upgrade to R2

Can my Clients, which are still at RTM (7711), still communicating with my Site, which will be at Version R2 (7958)?

Can i upgrade my Clients directly from RTM (7711) to R2 (7958)?

Thanks in advance :-)

It would not be supported even if you could. Just try it in a lab ...

Not sure on the communication -- I know they won't be allowed to initially be assigned when first installed, but they may communicate if already assigned.

Yes, to my knowledge, you can directly upgrade them though.
