Hi all,

I am trying to upgrade SLES11 SP3 to SLES12 but I am failing hard.

As described in the deployment guide I copied the kernel and the initrd to /boot and prepared /boot/grub/menu.lst with the update kernel.

It seems now that my old SLES will be deleted completely and a fresh install will be done. I have 3 Disks with / /var and swap from an SLES11SP3 and the Installer wants to delete the / partition even if I tell him to use it without formatting.

Is there a way to update via zypper on shell?

I tried and get a hell of dependencie errors.

In general I think the upgrade process is nearly undocumented.
