The reason is that RHEL 5 is based on Fedora 6, so the upgrade should
work out smoothly. Also if you haven't updated the machine so far, it's
best to update to a distribution that still has many years of support to
come. The software you have installed manually in FC5 should still work
in CentOS 5.

If, on the other hand, you really want to stick with Fedora, I'd do a
complete reinstall since that is the quickest way to do the upgrade
(doing 4 upgrades is *really* slow). Besides, that way you get a clean
system and all of the advantages of the new ext4 file system.

If you want to try your luck with the successive upgrades, you still
might end up with a bit of a broken system, since you will probably have
to recompile the software you have installed manually. Plus, you might
end up with some trouble with the upgrades themselves.
