I have a hub and spoke replication topology. A hub (server A) all branch servers (C,D and E) replicate to A and A updates all branch servers C,D and E. The Hub server A is running windows server 2003 R2 as such it is being decommissioned and replaced with a 2008 server. Once I have created the new 2008 server and its running DFS and added as a namespace server how do I update the replication topology for the new 2008 server to take the place of the Hub (Server A)? Is it a case of creating a new replication topology? I noticed when you launch the replication topology wizard it warns you that all existing connections will be deleted.
