How do we get POA to move my parents in rehab hospital?

Oh, I see. Initially, I misread the question. I thought there was already a POA who was refusing to cooperate with a move. I would listen to the attorneys advice, assuming the document is signed. Make sure it is Durable. I would also get one for Healthcare and a Living Will, if possible. I would discuss how you will need to use them in another state. Make sure they can be valid there.

I believe an Atty is going to have poa signed tomorrow the main problem is access to their income so assisted living can accept them??? Poa is family member of course transport but I believe I am going to fly

Could you provide a little more information about the situation? Like, is the POA a family member, have they refused to move the parents, have they explained their position, what is the benefit, is the problem money or transport, etc.
