 If path validation succeeds, the client SHOULD immediately begin sending all
-future packets to the new server address using the new connection ID and
-discontinue use of the old server address.  If path validation fails, the client
-MUST continue sending all future packets to the server's original IP address.

+future packets to the new server and discontinue use of the old server address,

+({{retiring-cids}}).  If path validation fails, or if the client decides not to
+migrate to the preferred address, it MUST continue sending all future packets to
+the server's original IP address, and retire the connection ID provided by the
