User blog comment:MisterWoodhouse/Fandom is upgrading to a modern version of MediaWiki/@comment-26569706-20190620150553/@comment-25252539-20190620152950

I think this thing can't be done in 2020 cuz Fandom is currently have ton of technical debt unlike Gamepedia which have "Hydra " allow them to easily upgrade MediaWiki while keeping functions work properly, however Fandom could provide beta test for wikis that doesn't have much custom codes so that they wouldn't ruin other wikis.
