That sounds like a good plan.  I think Mythbuntu is the only builtin
theme now - all the others need to be downloaded.  So if your restored
database is using any theme other than Mythbuntu, then you do not get
to see the question about updating the mythmusic database as that
happens before the theme is checked and you are allowed to select one
that exists to replace the one that is not installed.  So the best
plan for upgrading is to make sure that you start mythfrontend before
you restore your old database, and at that point make sure you install
the theme that is used in the database to be restored.  Failing that,
you can use the "-O theme=Mythbuntu" override from the mythfrontend
command line.  I had forgotten about that option as I have never used
it.
