My discourse site has a group that needs to migrate to a different self-hosted Discourse instance, under a different domain. Only the users of that group will go to the new instance. Is it possible to transfer only the private group messages that are in our inbox to the new instance?

Transfering inbox group messages to another instance?

I believe you can move regular topics, but for PMs, I don’t think there is currently a way. You may be able to do something with the API or rails console though.
