Indeed, what I have thought of is /primarily/ for Anaconda. Yum could 
also be involved, but first one thing at a time, a better finer control 
over the upgrade from within Anaconda for tasks where GUI does make 
sense for this would be a priority before making "networked upgrades" 
work with Yum. Simple stuff like being able to "choose" which users you 
want to migrate, nuke everything in the disk, except from chosen 
directories (/home/{user1,user2...n}, /root, /usr/local, etc), allowing 
the distribution to first get in place all the files and configurations 
it needs, THEN modify whatever files with only the information 
"salvaged" from the previous one. Getting that to be as clean and 
painless as possible should be a priority for Anaconda upgrading. Will 
take a look at the Wiki and see what other ideas can I toss around.
