I used mythconverg_backup.pl on the old system (Schema 1254) to backup the database and copied it over to a disk shared with the new system image.  Then I swapped out the 10.04 system disk for the 12.04 system disk.  I ran mythconverg_restore.pl on the 12.04 system and figured out pretty quick by running tail -f on the mythbackend.log that mythconverg_restore.pl didn't stop mythbackend and mythbackend didn't like the state of the database, so I stopped it with:

Did you stop the restore, dump the database and then restart the restore 
(with the backend and any frontends stopped)?

Checking the frontend log, I see that it reports the MythMusic schema (MusicDBSchemaVer) is 1017 and should be 1019.  It reports that it is waiting to see if it is being upgraded, times out, creates another database backup, and reports that the backup is complete.  That's the last line in the frontend log in the last 20+ minutes.  Meanwhile, the backend log is active, but not indicating that it is doing anything about the outdated MythMusic schema.
