We should use the outputs of https://issues.redhat.com/browse/OSP-17753 and try out the MariaDB adoption procedure manually. For things that should be implemented in the MariaDB Operator, we can hack around those manually (e.g. ssh into a MariaDB pod to import some sql files if desired, etc.).

DoD:

• Textual record of what was done - it does not have to be exact & reproducible record, but it should give the reader an idea of what was necessary to perform to make the MariaDB adoption possible (albeit manually).
• For any significant chunks that will need further attention, we should create Stories.
