If the account itself is like a property/attribute of a post/comment, then I suppose it can be changed seamlessly. But i dont think it is designed to be that way.
Afaik right now you’d have to send an update for every post/comment individually, if it would even work. I think we need one simple ActivityPub message that simply means “this actor is now this other actor, and all its objects should be updated”.
