Transport section 9.5 says "An endpoint MUST use a new connection ID if it initiates connection migration as described in Section 9.2 or probes a new network path as described in Section 9.1. ". 

Section 19.15 (NEW_CONNECTION_ID) says: "An endpoint MUST NOT send this frame if it currently requires that its peer send packets with a zero-length Destination Connection ID. "

I take this means active migration cannot happen with 0-length ID.

BTW: in a few places "zero length" used over the more common "zero-length".
