Hi;
How can I upgrade my Centos from 4 to 5.1?
make full backups of all your system volumes (/, /var, and so forth if
you have them as seperate volumes), shutdown and boot the CentOS 5.x
CD, run an upgrade.
this will probably work if your system is quite stock and you've not
installed any non-centos4 stuff on it. if you've got a mess of
stuff from non-RPM sources and/or nonstandard repositories, chances
are you''ll either spend about 60 hours picking through the pieces
trying to get it all sorted out, or you'll end up restoring your backups.
Personally, I recommend clean installs. backup your user stuff,
config files, etc, then wipe and rebuild the system scratch, referring
to the previous configs and stuff for reference.
YMMV.

I tried to 'upgrade' but ran into a number of problems some of which I
still have not resolved - Messages and boot log not being written to for
a start.
I would strongly recommend backing up the data etc and doing a
reinstall - I have spent more time fixing problems than the time to
reconfig.
