There are somethings that you just never get round to, my nagios box was still running whitebox linux, and I’ve finally gotten round “upgrading” it to CentOS… yeah ok, upgrade is arguable, but you get my point.

First off a warning: Don’t do this ! All the documentation, for CentOS, RHEL, Fedora, any redhat linux all say, clean installs are the best way, and upgrades are not advised…. therefore I offer no support or warranty that this will work, in fact, I you advise you to read this post, but step away from your consoles !
