CentOS 5.x and CentOS 6.x are MUCH more different, there is number of packages that are obsoleted and replaced with packages of same effect but with different config files, file locations, etc. Do what you like, but with such different changes, my servers will be freshly built and clean (I am slated to upgrade them in few weeks.) -- Ljubomir Ljubojevic (Love is in the Air) PL Computers Serbia, Europe Google is the Mother, Google is the Father, and traceroute is your trusty Spiderman...
