Having done several upgrades from CentOS 4 to CentOS 5, my recommendation would be to not even try it. There is all kinds of ugliness left over that has to be cleaned up; I did it in the end, but it took a lot longer than doing a clean install.

That's the point.

The cost to upgrade is probably higher than a clean installation.

It has changed so much between RHEL5 and RHEL6.

I recommend everyone a clean installation.

I think the only 'clean' upgrade I had was Centos 5.2 -> 5.3 and that happened by accident!

Errr, you should be able to 'yum update' any 5.x to any other with few surprises. Did you mean 4.2 as the starting point there?
