Copying all the mailboxes from server A to server B

Morning lords of Mailcow-Dockerized,

I plan to have a kind of “replication” server from A to B using this way:

• copy the MySQL “mailbox” table from A to B
• create syncjobs on B to synchronize messages received on A to B server

So my question:
1 - do you think this solution could work ?
2 - is there any smarter and more elegant way to do it?

Enjoy your coffee!

Ha and I nee also to copy quota2 at least.
