This is the appropriate way to move a database to another host or to 
restore a database after an OS upgrade.

Exactly.

MythTV 0.25 will upgrade a 0.24 database schema without problems.  So, 
as long as all of your systems will be running MythTV 0.25-fixes, all 
will work fine.

Just make sure you protect that pre-upgrade database backup well.  If 
you have any problems, it's your get-out-of-jail-free card.
