Question Accidentally upgraded to MariaDB 10.4

[goobliata]

Hello. I'm using Plesk Obsidian on Debian 9. I accidentally upgraded to MariaDB 10.4, so my databases got upgraded/etc. Can anyone help me to correct this (downgrade to 10.3) while preserving my databases? Most things are working fine, only thing I noticed is backups are not correctly backing up the databases (which is important.) Any help would be great!

I don't think yon can downgrade MySQL. Plesk does not support it.

I'm looking for a manual way to do it. So far my idea is to dump the databases then force install 10.3, then refresh the DBs. I don't know if it'll work though.
