Upgrade from 5.x to 6.x is not supported by CentOS.

"Red Hat does not support in-place upgrades between any major versions
of Red Hat Enterprise Linux."

It helps during their creation, rather than just accepting the defaults, 
to give the LVs meaningful names.  But even if you don't:

# df -H
Filesystem             Size   Used  Avail Use% Mounted on
/dev/mapper/VolGroup00-lvroot
                         31G    12G    18G  39% /
/dev/mapper/VolGroup00-lvtmp
                        195M    55M   131M  30% /tmp
/dev/mapper/VolGroup00-lvvar
                         21G   1.2G    19G   6% /var
/dev/mapper/VolGroup00-lvhome
                        185G    40G   136G  23% /home
/dev/hda3              518M    46M   446M  10% /boot


Where's the difficulty?
