Look for the thread named "Direct Update FC 1 -> FC6" on this list not
long ago. It has many opinions in there.

The summary of my opinion:
Small jumps Fn->Fn+1,2: Fastest is rpm -Uvh release.rpm directly to
the version you want, yum update in runlevel 3, inevitable cleanup.
Medium jumps Fn->Fn+2,3: Fastest is Anaconda to upgrade in one version
increments + minimal cleanup at each step.
Large jumps Fn->Fn+4+: Fastest is backup, reinstall, then restore
important personal data and settings.

This is flexible based on your ability to "cleanup" manually to
possibly get X working and get all the new config files in place ...
something that the anaconda updater makes a good effort to do for you.
If you have lots of experience doing this sort of thing, add some
jumps to each category. If you are a Linux-noob, subtract some jumps
off each category such that yum might not even be an option for a
complete neophyte.
