My existing home/dev install of Seafile is running Seafile 10.x Pro on bare metal Centos v7 which is of course EOL. So I’m looking at build a new Linux VM. Aside from which distro to use (a separate topic in itself), I’m planning to leverage docker tech as Seafile bare metal upgrades make my head hurt! I’ve often considered sticking pins in my eyes in preference to a Seafile bare metal upgrade 
But I’d prefer to migrate the entire configuration and data across. Any guides on this? I’m assuming the Seafile server stores it’s data in a both the MariaDB databases and the Seafile folder.
