I've never run a SuSe distribution but here is how I would tackle it,
based on a fairly significant upgrade I did from a RHL 6.2 to RHEL 3
system with over 1,500 users on it.
1. Don't even think about overwriting the system. Back it up and do a
fresh install.
2. Grab all entries from /etc/passwd, /etc/group, /etc/shadow, and
/etc/gshadow for all UIDs over 500. Look very hard at the ones below
500 - they're probably not required and are typically added by the rpms
for daemon-based packages (bind, etc.). For each of those users, also
grab /etc/samba/smbpasswd (or wherever smbpasswd is stored on SuSe - Red
Hat moved it between releases from /etc to /etc/samba).
3. Red Hat keeps its mysql info in /var/lib/mysql. Shut down mysql,
back it, copy the entire to another system, and start it back up. I've
done between 2 Red Hat systems and the database came right up.
4. Don't forget about the mysql ini files and php-mysql.
That's certainly not all of the steps required, but it's a good start.
