I am about to upgrade a Xeon workstation with FC2 installed on a set of software RAID-1 partitions to FC4. Does anyone have any pointers on what rpms I might want to deinstall first to prevent glitches in the upgrade? So far I have deinstalled the Sun java rpms since I know these aren't installable under FC4. I also have deinstalled the firefox 1.0.5 rpm I have installed. Lastly I will revert the graphics drivers back to the stock radeon ones and deinstall the fglrx rpm before the upgrade. I am still a tad worried as I don't know how anaconda responds during an upgrade if it finds a package installed which has conflicting file ownership (like fglrx does hence my decision to deinstall it). Thanks in advance for any advice. Jack
