Hi! I've inherited a SLES 11 SP1 server with a strange repository setup (about 800 of the 1400 installed packages come from openSUSE 11.4 repositories, the rest being from assorted SLES repos, the situation is similar to what's described in this thread). In its current state, the machine is kind of borked (all repositories are out of date) and I've got a couple of questions:
1. What's the best way for me to upgrade the machine to SLES 11 SP3? I really don't want to break things, since this is a production machine. Further complicating matters, SLES runs virtualized on VMware.
2. Are there any packages that are in the openSUSE-11.4-OSS repository that are not in the SLES repositories? That is, if I remove the openSUSE repos, would any packages not be updated at all anymore? Also, if yes, is there a way for me to check if there are any installed packages that would be impacted by removing a repository?

Here's my 'zypper repos -d' output:
