User blog comment:MisterWoodhouse/The first migrations to the Unified Community Platform/@comment-46630092-20201029201855/@comment-24006128-20201030144909

The legacy version was unable to be updated, meaning our dev teams had to spend most of their time working to keep it from falling apart. Since it could not be updated, but we needed to make it updateable, we had to start from scratch with a new install and then port stuff over to the new install, then move the content to the new install. That work is almost done, which means we can move onto new features, new designs, new extensions, and user-requested enhancements.

Message Wall, Forums, and Article Comments all operated on customizations of the core MediaWiki code. They were part of why we couldn't update the legacy platform. Moving them to the Discussions software allows us to keep the new platform up to date with MediaWiki releases, bringing new features, security updates, bug fixes, etc. from the Wikimedia Foundation.

And Balabala222, all wikis in good standing will be migrated. There aren't wikis we don't know about.

And practically nobody wears a suit at Fandom, anon user. Our CEO wears jeans to the office. Sometimes a Star Trek uniform.
