I agree with ACM and Beatriz, you can also look it up at the back of your green ID-card. It tells you, if and where you are allowed to go to. My friends in Brandenburg have restrictions to move until December and from then on, they can go anywhere. Important is, that when you move and change your living place, that you inform the organisation of your current residency and later on your lawyer, to avoid issues with the offices. Also when you have a house in Bonn already, make sure that you go to the municipal office and register your new adress - then everything should be fine.
