        # ---------------------------------------------------
        # WIKI 

        # Handling for the article path (pretty URLs)
        location /wiki {
                index index.php;
                rewrite ^/wiki/(?<pagename>.*)$ /wiki/index.php;
        }
        # Images
        location /wiki/images/deleted {
                # Deny access to deleted images folder
                deny all;
        }
        # MediaWiki assets (usually images)
        location ~ ^/wiki/resources/(assets|lib|src) {
                try_files $uri 404;
                add_header Cache-Control "public";
                expires 7d;
        }
        # Assets, scripts and styles from skins and extensions
        location ~ ^/wiki/(skins|extensions)/.+\.(css|js|gif|jpg|jpeg|png|svg|wasm)$ {
                try_files $uri 404;
                add_header Cache-Control "public";
                expires 7d;
        }
        # License and credits files
        location ~ ^/wiki/(COPYING|CREDITS)$ {
                default_type text/plain;
        }

Migrate the database

On our old OVH server:

mysqldump --user=wikidb_user --password=wikidb_userpassword wikidb > file.sql

On our new Servus server:

Update!

php maintenance/run.php update

Then this error appeared: Class "Wikimedia\Parsoid\DOM\HTMLDocument" not found

Followed this: https://phabricator.wikimedia.org/T409283

And this response worked:

The problem is that Wikimedia\Parsoid\DOM\HTMLDocument isn't properly autoloaded. I solved it temporarily like this:
require_once('vendor/wikimedia/parsoid/src/DOM/HTMLDocument.php');
Insert this line right before $doc = HTMLDocument::createEmpty( "UTF-8" ); in vendor/wikimedia/parsoid/src/Utils/DOMCompat.php.

Worked!

Done
