Well, this is a silly question (sorry) but what happens if I make an upgrade from one Ubuntu LTS to another (in my case 18.04 to 20.04) plus a PHP upgrade?
I made a backup of my database and the MediaWiki folder and secured it, but how will the software react to this changes? Do I need a reconfiguration after that? Does I get an error due to the changed OS/PHP version? Or will nothing at all happen?
It is a very silly question, but hey, better asking it now than after having a problem with the upgrade.
