So, if I migrate an account, is there a way to get back to the previous instance without much pain? I'd like to try the iceshrimp thing as a main account...

@noel Don't migrate, just export/import your following list. Let people follow you back when they get the incoming follow requests.

Migrating doesn't move any of your posts or anything anyway, only stuff you could move manually, so it's basically pointless and comes with a MAJOR risk of losing everyone.

@IceWolf yeah, currently looking into that, seems to be a bit more involved in iceshrimp...
