Tootfinder

I'd really like to find a way to migrate a domain (and existing account & posts) between two pieces Fediverse server software, keeping all post urls.
Not the existing Move feature - that assumes new & old servers are running in parallel at different urls.
I want to take a backup from Mastodon, stop the server, convert all the toots to some common format, start up GoToSocial, and import. Without losing reply glue on old toots or spamming.
