Need to move configuration channels to secondary Satellite server

I need to not only move software channels from a primary Satellite server to a secondary server, I also need the configuration channels moved to the secondary server. I am running version 5.6, and thought the ISS function would work. But my Satellite servers are running in "disconnected" mode, and it appears the syncing only works in "connected" mode. Someone tell me if I'm wrong in that assumption. Any further knowledge or insight would be most helpful. Thanks.
