I suggest you backup your data first if you do this. A FC(n) ->FC(n+1) is reasonable but still not really recommended, normally it works for most people. FC(n) -> FC(n+2) is not so well tested...
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.
