I am also interested.
It sounds like performance of the internal DB has really improved since ‘back in the day’ when I moved to MariaDB in a Docker container. I would love to use a unitary backup solution that would include the DB primarily for situations where bugs in new releases have me downgrading.
That’s my motivation for wanting to move back and I’m okay if it has to be a clean database. I will have to give this another read sometime soon: Migrating from MySQL (mariaDB) back to sqlite - #8 by mneuron
