I recently upgraded from 0.21 to 0.24 (three times because it kept recording new shows before I had time to migrate all of my systems) using the mythconverg_backup and mythconverg_restore scripts. The process went very smoothly each time. In my case, I used a separate hard drive to do the new installation on so I was guaranteed to not lose data, but it wasn't a problem in the end anyway. I wrote up the experience here if you want to take a look: http://www.missingremote.com/guide/migrating-mythtv-database-between-installations
