I just migrated a community from Lemmy to Piefed using the migration feature, it worked quite well

Context: I tried to use the Piefed migration feature to migrate [email protected] to [email protected]

https://piefed.social/c/barcelona now exists, with all the existing posts there, as well as the icon and description.

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/[email protected]), 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.
