Well, nicest thing would be for messages to be replicated out to the new
node (if that is the configured HA policy). But I get that this is
hardish and costly.
But having an API-function to be able to migrate all HA-queues from one
node to another node would be awesome when the need for maintenance or
upgrade comes up.
When using HA-queues CCN is a must anyway, right?
