Re-route Mail in Queue on Cisco Ironport C360

We have 2 Cisco Ironport C360 email security devices on our network. One for our European network, which routes our EU Exchange infrastructure, and the other which sits in Cincinnati and routes for our North American Exchange Infrastructure. Today our ISP connection has gone down, so we can't send or receive email though our Ironport. I have modified the exchange environment so mail is now routing in and out of the Cincinnati Ironport (different MPLS WAN connection), however, there are still emails in the queue on the EU Ironport and I can't see how to route there thought to the other Ironport?
Any help appreciated

Resolved following tech call from Cisco. Details to do this are:

You can use a ‘hidden’ CLI command ‘redirectrecipients’ to do this.  
To force the queued messages waiting for delivery off the current IronPort device, you may want to push them over to the other IronPort appliance to attempt delivery. Please follow the steps below.
• Logon to the second IronPort appliance and add the IP address of the old IronPort device to this machine in the Relaylist of the HAT Overview section ("Mail Policies > HAT Overview"). Once you add the IP of the old machine here, you can push the queued messages from the old machine over to this one.
• To redirect the queued messages, run the command "redirectrecipients" on the old device. The system will then prompt you to put in the IP address of the inbound listener of the other machine. You are basically transferring the messages from the old machine over to the other machine to attempt the delivery.
• To verify there are no more messages waiting to get delivered, type "tophosts", then select #1.

Ensure the IronPort with the queued messages can connect to your US IronPorts before running the command.  The easiest way to test is to do a manual telnet on port 25 from the IronPort with the queued messages: telnet hostname 25

How do you turn it off when you are ready for the Ironport to start processing its own mail again?
