This also means I'm almost not really upgrading anything.
FC5->CentOS5 is similar to FC5->F6
(ok, with some backports, I know)

I have no manually installed software.
One of the reason to prefer Fedora (possibly a recent one) is that
the software I need has been already properly packaged with high
probability.

In my specific case, converting the system disks brings no advantage
as they are never really accessed. As regards the data disks instead
(this are fileservers in a rack), I would certainly avoid ext4 for
some time for safety. The data is currently on reiserfs, whose
quality is often estimated a lot worse than the actual thruth.

I'm actually considering a 5 to 11 upgrade by DVD.
I hate reinstalling.
Doing it in many steps would probably not be much better.
Some initrd issues, rpmsave/rpmnew cleanup etc are not a problem
for me. Graphical login is almost unused, so I don't think something
awful can happen for apps I'm interested in: ntp, samba, netatalk,
cups.

The system is on RAIDed disks, so I will disconnect one of them
as an easy rollback chance in case of unresolvable issues.

The machines are actually not mine and they are used in production.
This is why I'm didn't upgrade in the past (except FC4->FC5).
They work perfectly and the only thing which is pushing me
is the lack of SMART support, which I find unforgivable for a file
server (yes, yes, it is all properly backupped :-) ).

Thanks to everyone giving advice.
