It might also be possible to force Anaconda to do the upgrade.

Thanks John.
Basically if you have done updates to the system.. you will have
'orphaned' packages. Fedora Core 5 and 6 kernel, glibc, (or other
things) have higher rev's than what is in CentOS-5. The best fix is to
do a backup of /etc and other config files, backup your /home
/var/I_do_stuff_here partition and install a fresh CentOS-5
A couple of suggestions for doing the fresh install and minimizing
some of the pain.
1. tar /etc to someplace safe. While you cannot just restore the
files,
you can use them as a reference. There are pieces of /etc/passwd,
Restore /etc to, say, /fcetc, then use diff to discover what's changed
Some differences won't matter (or are right)
Some differences will need interpretation: why is this different?
Some will need special action - eg creating user accounts, preferably in
the same order as before
Some can just be copied.
