mixed zenworks versions

ZENworks 7 SP1 is currently installed/running on NetWare 6.5 SP7 OES.
I'm doing some testing in preparation for bringing a new ZENworks 7 SP1
IR4a server online running on SLES 10 SP2 + OES2 SP1. The two servers
will run concurrently for a period of time while I migrate data/services
to the server running IR4a.

My concern is that the IR4a install will introduce schema extensions,
updated snap-ins, etc. I suspect I will need to cautious when working
with ConsoleOne.

Thanks.
