# FEP-7628: Move actor
@@ -18,17 +19,15 @@ Migration of followers from one [ActivityPub][ActivityPub] actor to another.
Mastodon started using [`Move`](https://docs.joinmastodon.org/spec/activitypub/#Move) activity for migrating accounts [in 2019](https://github.com/mastodon/mastodon/pull/11846). The activity is sent by the old server to actor's followers and actors who receive this activity un-follow the old account and follow the new account.
[Streams](https://codeberg.org/streams/streams) implements [Nomadic Identity](https://codeberg.org/streams/streams/src/commit/11f5174fdd3dfcd8714974f93d8b8fc50378a193/FEDERATION.md?display=source#L54-L59) mechanism, that makes identity independent from a server. Nomadic accounts are currently not supported by ActivityPub but are available via the [Nomad protocol](https://codeberg.org/streams/streams/src/commit/11f5174fdd3dfcd8714974f93d8b8fc50378a193/spec/Nomad/Home.md).

## Linked actors
One persona can be represented by one or more actors. Different actors are considered associated with one persona if and only if they are **linked**. Possible ways to link actors:
- `alsoKnownAs` property of an actor object. This method is used by [Mastodon](https://docs.joinmastodon.org/user/moving/#aliases).
- `alsoKnownAs` property of an actor object. This method is the most popular, it is used by [Mastodon](https://docs.joinmastodon.org/user/moving/#aliases) and many other ActivityPub servers.
- [FEP-c390][FEP-c390] identity proofs. Actors are linked if they have identity proofs with the same `subject` property.
- [rel-me][rel-me] links. Actors are linked if their profile metadata contains verified rel-me links pointing to the same website.
