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
ways in mdv, but nobody probably tried this yet.

Not currently planned.

</I>
A switch in architecture is not really ugly - the package database
supports this.
