@ianswett 
> The 5-tuple doesn't change during the handshake. That means we should not send Handshake packets down the new path.

I agree.

Assuming that is the case, we need to define a mechanism that allows the server to drop Handshake keys and the path before migration completes, or even better before the sends the first packet in response to a migration attempt. Otherwise, the server would be required to have a special-case for handle the original path.

Proposed solution is #3141.
