I'm looking at doing an upgrade of a ZCM system with two servers, both running SLES 11 sp1/ZCM 11.2.4. From what I've seen so far it looks like I have to upgrade to ZCM 11.3 first and then to 11.4. Two questions that I can't seem to find clear documentation on.

1. What issues may I cause with ZCM upgrading SLES to 11 sp2 (or higher), i.e. will there be package conflicts that cause problems? And if so, what processes are used to mitigate those issues?
2. Is it possible to migrate from server to an appliance, and is there documentation that outlines that process?

Thanks for any assistance.
