FactoryTalk Admin Console - copy OPC RSLinx Pro from primary to secondary redundancy

[scotthower]

Running redundancy for OPC topics (RSLinx Pro is the data server)...switched from primary to secondary so that I could add topics to the primary without affecting data collection - I thought that there was a magical way to synchronize the new changes from primary to secondary? I'm nearly certain I remember doing something like this in a lab but I haven't found any documentation anywhere on the web or within RA. Thanks!
