As the title states I would like to migrate to another server/provider (currently I am on matrix.org). Is that possible, without losing my chat history. I heard, that there is a tool, that invites your new account to all chats. But wouldn’t that make my “person” chats to group chats?
The feature your interested in is called portable identities and is still in development, as far as i know. As far as matrix is concerned there is no difference between a personal chat and a group chat. There are rooms with members, thats it. Maybe the tool can kick your old identity after a successful transfer though. Hope this helps a little :)
