[Koha] Migrating from one server to another

(Note: I am not using "migrate" as it is usually used today, meaning switching from ABC software to DEF. I'm referring to relocating an installation's data.) I would like to migrate my data from one Koha installation on one server to another installation on another server. Both use MariaDB. Where are instructions suitable to migrating data between two different servers? Thanks, Br. C.S. Hayward
