Upgrading 9.0 to 9.2

Greetings - I have backed-up my files from my SuSE Pro 9.0 system with Ximian XD2 to a DVD-R. I have the SuSE Pro 9.2 box set and am getting ready to upgrade using the DVDs. Before trying a "clean install," I'd like to try to simply upgrade 9.0 to 9.2. I'm reading the manuals, checking out fora and messages boards, etc. I'd appreciate any tips that I should pay attention to from those who have already done the upgrade. For example, should I expect any particular difficulty trying to upgrade Ximian (GNOME) desktop environment (XD2) to a SuSE GNOME desktop? TIA Kelly -- Kelly J. Morris
