User blog comment:Brandon Rhea/How we're testing the fandom.com domain migration/@comment-35972039-20181006115135/@comment-20644-20181006144218

The current 3,200 wikis that are being moved will have fandom.com in the URL, while all other wikis will stay on wikia.com for now. But those other wikis will also be moved over the next few months. By the beginning of 2019, all wikis will be on the fandom.com domain.
