I'm getting Bluesky installed next week, is it possible to have Bluesky running with the old Gateway system in the same time? We have a whole bunch of stuff recorded in the old Gateway. My thought is to have both systems connecting to the same TVs, e.g. old Gateway on HDMI 1 and Bluesky on HDMI 2. Can this be done by splitting the existing cable from wall to TV, one connects to the old Gateway portal and one to Bluesky?
