User blog comment:MisterWoodhouse/The Unified Community Platform Editor and our first release date/@comment-37855715-20200316215216/@comment-24006128-20200316223522

Existing wikis will remain on the old platform until the new one is feature-rich enough to support them. We will not be bringing the old editor options forward, as they are either no longer supported with active development or not as good as Wikimedia's 2017 Editor.
