Is it possible for a second broker (version 8.0) to be a broker client to another broker (version 6.5) and subscribe to specific documents being published - without using territories.
The reason for doing this is a staged migration from broker 6.5 to 8.0. I would want the 8.0 broker to get only a subset of documents from the older broker. I am hoping to do as little to current production server as possible (hence the reason in avoiding setting up territory on 6.5 and 8.0 and then using gateway).
Am I trying too hard and should I just set up each broker in a territory ?
