How to update fropm OpenSuse 10.1 to 11.0?


I am still running OpenSuSE 10.1:\ and need for some reason to update to a more recent version. I tried using the System Update functionality of YAST, but always get the message that the versions are not compatible.
As I have quite a lot of applications like Oracle Database and Mail-Server installed in addition, I will need an update and not a new installation from scratch.
Any advise how I could get this on the way?
I have the DVD’s for OpenSuSE 10.2 and 10.3 already, but am not sure if those are the right medias.

Thanks for an hint.
Best regards,

Fresh install!

Best you can hope for is keeping /home
but I think I would prefer a data backup and format everything.

Is it possible to run an upgrade simulation using a backup store? Or on your production instance, with a verified backup you can restore from?

I’ve been able to do an upgrade similar to yours, but you really need to be comfortable doing some hacking. Alternatively, while it would be time consuming, you probably could do it one version at a time, that is, to 10.2 then 10.3. IIRC the 10.1 to 10.2 was pretty trivial; issues were with the package manager. Same with 10.2 to 10.3, but there is a critical gotcha there where the disk controller driver is switched to libata and the drive numbering may need to change from hda to sda, etc. Using the DVD for 10.3 you could at the partitioning step use YaST to force a re-write of /etc/fstab which will deal with that. 10.3 is still supported, so you could stop there and digest that without moving to 11.0 just yet.
