When the admin of a instance wants to stop the server (for example costs are running too high) but your communities are active and you don’t want them to die along with it, is it possible to migrate the communities to another instance?
This is currently not implemented, but at least moving over subscribers to a community on another server is in principle no different to account migration on Mastodon and will be probably implemented sooner or later. Moving content over is another matter and IMHO unlikely to happen anytime soon.
In my own experiments with ActivityPub’s lesser-known client-to-server protocol, I found that it was possible to author messages that predate whenever a message is posted. Theoretically, this could open the door for importing statuses between Actors.
At the very least, a migrated group would just need to perform an “Announce” activity on the old group’s messages to mirror them, up to a point. I’m not saying that it would be ideal if thousands of messages needed to be moved over, but maybe there are smart ways to optimize that that doesn’t require thousands of cross-server requests.
not really, you can just start advertising the new community
