There were ideas about the MariaDB adoption floating around - should it be done by tar.gz of /var/lib/mysql, or should it be written out to .sql files, or should it be streamed between DBs? We should bring some clarity into what we expect to implement.

We should involve MariaDB experts.

DoD: Textual representation of how we want to perform MariaDB adoption. Some worthwhile aspects that should be discussed and documented: how we want to do the data transfer (see above), what parts are likely to be done manually, what parts are likely going to be implemented in an Operator.
