I’d be also interested in understanding this.
I have to admit that I am not sure if there is anything else that uses MariaDB, as I had installed this years ago and since then it is just there. Any way to find out if it can just be deleted?
Generally: After the update it is like a fresh install, but frontend has not changed, so you jus creae the same connections again? Does it also recreate the SSL certificates or use the existing ones? Somewhere else I read about error messages that the certificate would already be there.
