An officially supported one-off path exists for moving a single-user Akkoma or Pleroma instance onto littleFedi on the same domain, keeping the actor URI and the RSA key pair so that remote servers never notice the switch. It carries the identity, the profile, the followers and the following list. It does not carry old posts or media.
Would this work or be possible for Gotosocial or Mastodon too?
