I have not had much luck moving poppies. If they are tiny enough, I have succeeded in moving a shovel full deeply dug so as not to disturb the roots and babies, then gently placed in a predug hole the same size without moving the dug dirt any. Then water gently and well.
The perennial oriental poppies may survive if kept damp for a few weeks until the plant is actively growing again. If you let it dry out, it will die. They just don't like to be moved, unfortunately.
If necessary, just give it try with a few at a time and see how it goes.
Poppy seeds need a cold winter to germinate and very little soil on top. Where I used to live in southern Ontario, I sprinkled my poppy seed on the garden in the fall for sprouting the following spring. I have no idea if I can do that up here, or not. I'll find out.
