It is not officially supported, but in general, I do upgrades via yum, and this seems

FC12 yum upgrade notes
One of my systems was tangled up with a bunch of dependencies involving every php package
known to man. I gave up sorting it out and decided to do the upgrade from the install media
(on DVD), here are some notes on that:
FC12 DVD upgrade notes
A variety of fixes are suggested, including:
If you get the nvidia driver from rpmfusion, (as kmod-nvidia)there is some confusion about what repository it is in (look in the updates-testing repo).
If you are into using compiz with desktop effects there may be other issues depending on your exact graphics hardware and which nvidia driver you are using.
See notes at:
The drivers are found in /usr/lib/xorg/modules/drivers or /usr/lib64/xorg/modules/drivers on a 64 bit system. If the proprietary driver has NOT been installed, you will see these two files:
nouveau_drv.so nv_drv.soYou can pick one or the other in the /etc/X11/xorg.conf file (if you have one). The lazy approach is to stick with the default (nouveau).
Note that error messages end up in /var/log/Xorg.0.log and/or any number of files names /var/log/Xorg*.
