Upgrading from Suse 9.3 to 10.2
Hi, I'm new to linux (and this site), but I'm a computer technician at my university (mostly windows computers) but I'm responsible for upgrading 5 Suse Linux computers from 9.3 to the current 10.2 OS. I need to make sure all the settings, software, user accounts (about 30 of them), and data files all remain in place and intact. I've done a few linux installations from a freshly formatted hard drive, but nothing where i've just needed to upgrade and retain everything.
How do I go about doing this? Is there an option when booting from the installation DVD to do this?
