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’m talking purely from an ActivityPub/Activity Streams/Activity Vocabulary/JSON-LD perspective. There are some other local identifiers for things in Lemmy, but those do not matter for the purposes of federation. Any Object that is federated is expected to have an ID that is a URL at which you can make a GET request with the proper Accept header and you will get the latest version of that Object. AFAIK there is no provision for IDs to change.

Not the url.
It may be that the url is linked to the ID. And that ID can just change.
I’m pretty much a noob. Just a lurker on the matrix chats.
