Communities are inherently tied to the instance on which they are created and cannot be moved. If the instance is overloaded then that community will not federate properly. If the instance goes down nobody can post to the community. If the instance goes away that community goes away (except for the "cache" that other instances have).
Hmm. I’m not sure if that’s the case. I’m interested to see what the plan is for account migration. Weather posts will follow the user. Or stay with the instance.
Migration of ActivityPub stuff is pretty rough... Everything has an ID, and that ID is the URL, so the ID of the post you replied to is literally
https://lemmy.nrd.li/comment/227095... AFAIK there are some (non-standard, at least not in core AP) ways you can mark things to be like "yeah, this moved to over here", but that isn't built in to the spec so whether those mechanisms actually work is a crapshoot.I think we should expect/aim to just have some "mass repost script" that can take an extract of a community's content and just "repost" it on a new community.
Basically, a script that would "replay" a community in one go. I don't know if you could create "new comments" that immitates perfectly the original commenter but that would be the idea for a quick and very dirty "community mover script".
A bit like in GIT when you want to change/remove a specific commit, you can only replay/rebuild everything from the start by creating new everything posts/comments.
Or maybe that's a terrible plan ;)
