Hi - I'm new to the AlwaysOn game and I'm attempting to setup a new test environment. Currently I have two servers in two different locations - let's call the HQ and DR. I have a SQL instance setup (DEV) and an AG (HQ is primary) between the two of them. I'm have a second instance installed named STAGING that I'm attempting to create an availability group with. I'm getting the error that I cannot use the same port. How should this environment be setup? At the moment we have 4 separate instances in our current environment (DEV, STAGING, TEST, PROD) and we'd like to keep those instances. Is there a way to host all four on the same two nodes with AlwaysOn/AG and keep them as separate instances? Or do we have to have one instance and just make different Availability Groups? My concern is in the 4 environments, we have databases with the same name in each. I don't know how that would be handled with a single instance.
Sorry if this is not clear. As I said I'm still in the learning process.
Thanks!
