You are comparing 2 different things. What you are seeing is a
'finished' release of 6.x to latest CentOS-6 which is much different
from going from say RHEL-6beta to CentOS-6.
Betas of RHEL have normally had major changes between beta and final
versions. Going from EL6beta to EL6.0 or EL7beta to EL7 required some
manual work each time for anything beyond the base install because
packages were removed or settings changed majorly between them.

If you have the time to play around with it, then sure you might make
it work.. you might also wipe and reinstall.
