Forgot that one ;-)

 How about when the instance is attached with volume? How to migrate the

There is a dirty hack that you could perform for that. What you could do is
(depends on your storage backend):

- detach the volume from project A
- create a dummy volume on project B
- make pointed the volume from project A to the dummy in project B
- delete the volume from project A

If you use Ceph RBD it's really easy for example.

For the rest I don't know.
