The trick there is to specify the "upgradeany" switch - otherwise no
supposedly-upgradable system is found. My conjecture is that this is
because Red Hat discourages upgrades. A clean install with backups of
config files (and likely /home, and possibly /var/www and /usr/local)
available for customizing is still probably the best bet.
