It's a 2007's 1.9.2 MediaWiki, on a MySQL 4.0 version. The only serious extension was Semantic, but not overly used. The content is mostly French, with a sprinkle of Polish. I need to update it to the last MediaWiki and a somewhat recent MySQL & PHP version.
MediaWiki is at least theoretically able to upgrade its database schema from any old version to current one for your chosen version, by running the maintenance/update.php script. (Not sure how well Semantic extensions handle that, but probably also well enough.) As long as you manage to upgrade MySQL and PHP to a compatible version, that is :) https://www.mediawiki.org/wiki/Compatibility#Software_required_to_run_MediaW...
