An important point to capture here is that the server is responsible for ensuring that the connection IDs are not bound to one or other address at this stage (if migration is successful, later ones might be).  Thus, the connection ID in the transport parameter is no different to any other connection ID; it only exists here because using the new address is unusable without more connection IDs being available.
