EDIT: Oops, using MySQL (MariaDB).
EDIT: Deleted redundancies that made me seem stupid.
It has been so long since the Kodi 16->17 upgrade that I can’t remember how it went, and it might have (probably has) changed with the 17->18 upgrade, anyway.
I have five clients, two RPi3, one Vero4k, one Vero4k+ and one Windows 10. When I apply the April update to the first one, obviously it will migrate the database. What will happen with the subsequent device when the April update is applied? When the client sees that the new databases already exist, will it exit the migration and continue?
Just trying to avoid any surprises.
