@lumii @ozzy first part is how I do it
second way is a link to a guide on how to migrate
I have never done the 'official' migration way so not sure if it is actually better

Testing Account Data Transfer
Example
Export Followed users, posts etc from [email protected]
Create new account on new server [email protected]
Import followed users, posts etc
This way might not import attachments nor boosts.
