If you have a working MythTV setup, and you want to try a newer version, both the software, and the database, need upgrading.

Usually, a newer version of the software will handle this automatically – even creating a database backup beforehand.

If you haven't upgraded in a long time, however, there might be problems. e.g. the program might say:

Your database version is too old to upgrade with this version of MythTV.
You will need to use mythtv-setup from MythTV 0.22, 0.23, or 0.24 to upgrade your database before upgrading to this version of MythTV.


The mythtv programs give some useful information if you use the -version argument:

mythbackend --version
Please include all output in bug reports.

but that doesn't help you to understand the database, or plugins.
