ESA support group to UC

Hi having just read the latest newsletter I wondered when this mass migration was happening as I am in the support group of ESA, would it entail going for another assessment or just a case of making a new claim for UC, incidentally I live in Scotland but don't know when the Holyrood government are supposed to be administering their own benefit claims any thoughts ?

The migration will not start before the end of 2019, our current understanding is that existing awards will be moved across.

As far as I am aware Scotland is not taking any ownership of UC.
