I dont think many people use link to hub/hub link any more. The preferred option is HubConnect, which from memory, is the official recommendation (although I could be wrong).
HubConnect is fantastic, and once set up correctly, doesnt put any extra strain on the old hub, since the old hub is already sending out that information. The new hub (server) just listens.
HubConnect is here. Best to read the first post, and maybe the last 200.
