I've just installed CentOS 5.6. What would I get if I upgraded to 6? Would I have to reinstall all applications or could I just restore my /etc and /usr directories and do an update?
Thanks, John

Well, CentOS 6 is likely to be somewhat different than 5.6 -- lots of stuff has changed. You would get newer base versions of various packages and a newer base kernel. Otherwise it depends...
You'd have to do a fresh install, and then using a backup of your /etc as a guide, re-configure everything. If your system works just fine with 5.6, *I'd* say leave it alone for now. I am certainly not in any hurry to upgrade.
Thanks, John

I have written a set of bash scripts to do just that, ie a fresh install and configuration. They are highly extendable and configurable, and written in a modular fashion. Originally for Fedora to deal with the twice yearly upgrades, but I have also used them for installing Centos 5.5, which appears to have now upgraded itself to 5.6

Ponies.

There is no official upgrade path from 5.x to 6.0. You will need to do a full reinstall.
That being said there will likely be unsupported methods published to do such an upgrade; but it won't be supported and it may be prone to issues that are hard to troubleshoot.
There is full documentation, including feature comparisons and such, available at the upstream vendor's site:
