We are looking to deploy a second primary as our test box on a different subnet that can still communicate with our prod primary. The testing primary will only be connected to test applications, a separate domain, and used for upgrade and feature testing. Support said that we can use the same production license as long as the the two primaries cannot communicate with each other. I have been unable to find any information on what issues this could cause if both primaries can communicate with each other. Would this cause problems with the replicas attaching to the new primary? Any information would be greatly appreciated.
