Hmmm. Upgrades are spotty at best. I've done a few and gotten them to
work, but not without a struggle.
The most common problem is that the system doesn't purge old FC5-based
RPMs from the database and the system will try to continue to update
those old RPMs and run into a lot of conflicts, dependency issues, etc.
Some config files don't get updated, the ld config isn't always updated
cleanly, the yum repositories are different, etc., etc. Keep in mind
that F7 uses some FC6 RPMs, either because the old FC6 rpm was adequate
and there was no need to spin an F7-specific one, or the functionality
was moved to a different RPM.
To be honest, I'd do a fresh install of F7. FC5->FC6 is probably
doable with minor efforts. FC6->F7 is doable as well (this machine
is an FC6->F7 upgrade). FC5->F7 is probably too much of a jump.
That being said, if you have a good backup and you have the time to futz
with it, give 'er a go!
