I did an upgrade from F4 directly to F6. I had a few minor problems but nothing significant. For example, Dovecot wouldn't start with the old conf file. I had to switch to the new one. SquirrelMail wouldn't work until I fixed a php problem. I turned off virtually all services and started bringing them up one at a time. It was a lot easier than having strange things happenning and not knowing where to start. My biggest problem was trying to decide at the start if my system was hung. It took over an hour for the upgrade to actually start.
