I've tried it. It worked as designed* though with a surprisingly amount of lag (it took an hour or so for all my followers to move over). *As designed, it only automatically moves people who follow you, not the people who you follow, your bookmarks, posts, etc. There are also import/export functions for the list of people who you follow, and your bookmarks, and some other things I think that I didn't export. Those also worked, but it un-sorted my bookmarks (which are otherwise sorted by date added). Additionally (by design) this sends a new notification to everyone that you follow, that you followed them, and it requires people who have it set so they must approve followers to re-approve you as a follower. This wasn't a problem for me, but it also (unsurprisingly) doesn't move followers who are on an instance which has been de-federated from by your original instance.
