Is this with Broker?
If yes, are the documents still in der server side or already in the client side queue?
Warning: All this comes without warranty and on your own risk.
The safest way I can imagine of is writing a short code which takes the documents out of the queue and republishes them.
A more tricky way: If the documents are on the client side queue (assumed you create a new queue via a different client prefix on the new server): You can hook the new server to the existing queues by using an identical client prefix (this is done for clustering). But you must be very careful, IS will create new additional queues for all triggers if you change the prefix. So if you change them back, you may have duplicates.
