can anyone give me some advice for a method to upgrade a remote server from
rh9 to fc2?
Attempting a direct upgrade install from rh9 to fc2 using the same root filesystem is an invitation for disaster. There are cases when it works, and cases when it does not. Can you afford to find out which case applies to your system? Perhaps you can, if you have a good, tested, reliable, trusted, complete backup before you start.
From comments around work here, I would not recommend an upgrade to FC2 but a clean install. Some people are still trying to sort out problems related to the upgrade. I still have many broken links on my system from an upgrade that I keep finding. Some have had to resort to a clean install after tryint to get their older install to work.
There are so many changes between FC1 and FC2 let alone RH9 to FC2 that alot of time could be saved by doing a clean install and re-configuring.
Make backups and work from those.
