It even moved some subscribers (there are around 100 now), from what I understand those were Piefed subscribers that got automatically moved.
The one caveat is that from Lemmy instances, the community doesn't have show old posts (see https://lemm.ee/c/barcelona@piefed.social), but if you were restarting a community from scratch you wouldn't have access to your old posts anyway.
This ensure that at least the posts are transferred to a community on an active instance, which is probably the main concern for lemm.ee communities at the moment.
