+You can look for all config files you changed (probably using an rpm 
+command) and copy/merge those on the new system. Can be quite a bit of 
+work.

+You can wipe out the package database, but then after installing all 
+non-automatic installed packages, you'll probably have many files 
+unaccounted for (not owned by any installed package). Not a good idea 
+probably. Also all pre/post install scripts will be ran in new install 
+mode instead of upgrade mode. I did something like this with a VM (that 
+isn't very important to me) and I'm still finding new problems in it (but 
+it works anyway).

+There is supposedly a script that can convert the package database both

+
+Not currently planned.

+
+A switch in architecture is not really ugly - the package database 
+supports this.
