Red Hat has taught me well.  It has been *many* years since I have 
upgraded from one release of an OS to another.  I have experienced, and 
heard of, too many horror stories.  Mostly with systems that have had 
software installed from other sources, or non-RPM software, but I've 
never seen a sufficiently useful server that had only software from it's 
maker's repository.

I always back up my data, /etc, /var, /home, and some other directories, 
nuke it from orbit, and install the new OS.  It just works, I know when 
I'm done all the software will be compatible[0], config files will match 
the new software, old crufty stuff I forgot about over a year ago won't 
continue to fill up my hard drive, and updates will continue to work.


[0] Well, except for that gcc version messiness Red Hat pulled a few 
versions ago.
