Great, thanks...so to confirm, Pausing will stop new connections but process out the existing ones?

In my primary AD site, I have 4 Exchange 2007 Hub Transport servers. One of them needs to go offline for a couple of hours whilst it's moved to another part of the computer room.<br />
<br />
Unfortunately, we are a 24/7 operation. <br />
<br />
When I power down the Hub Transport, I need to ensure that are no messages in the queue.<br />
<br />
Does anyone know the best process for this? If I randomly check the queues of our Hubs they sometimes do have messages in the queue, not a lot, but a couple, then drop to zero, then up again, really depends on how busy we are.<br />
<br />
Is there any way to stop mails coming into the HT but let it process the ones in there? I was thinking of perhaps Pausing the Transport service, but I guess this will prevent it processing and sending messages in the queue too.<br />
<br />
Or, when a HT server is rebooted/ shut down, does it flush the queues anyway?<br />
