Surely an yum upgrade from FC4T3 to FC4 final would work better than

In theory.
However, "upgrading" from the latest test release sometimes includes
downgrading to a more stable package if something didn't work out during
testing. This is a failure mode that is not present in stable to stable
updates.
Also, there is more cruft (misnamed config files/options, bad
dependencies, etc.) that gathers during test releases than stable
releases since there is no commitment/promises made during test releases
to clear it out.
Those are the sorts of things that cause the most grief and require
manual intervention in my experience.
