Upgrade SuSE 8.0-9.1

Hi all, Just a quick one, has anyone here upgraded (or tried) a SuSE 8.0 server (not sure if it's pro or personal, running only samba as far as I can tell) to 9.1 Pro? How did it go? Anything to look out for? Thank you -- Kind regards Hans du Plooy Newington Consulting Services hansdp at newingtoncs dot co dot za
