On my production systems I only do fresh installs when moving from 
something like RHEL 3 -> 4. Also I don't upgrade a machine unless I have 
to due to end of life or a requirement for a feature offered in the new 
version. The many years of support and security patches is what drew me 
to RHEL and CentOS on my servers.
