I think the only 'clean' upgrade I had was Centos 5.2 -> 5.3 and that happened by accident! I have always taken the path to rsync all valuable stuff over to another box, do a clean install, then move stuff back. I have a set of instructions on 'customizing' for each of my systems to follow. I just added a 1.5Tb USB drive on one system that I am now using for the rsync destination. I figure that when I need to update the system it is normally on, I can move it to another system...
