First time caller, long time listener.
I have a situation where I need to stand up a single server Availability Group for around 2 months (i.e. move DBs to a new server, rebuild the current server, and add the rebuilt current server to the AG). Both servers are physical and have roughly the same specs. Windows Server 2016, SQL Server 2014.
My thought was to stand up the AG with the listener now so that when the current server is rebuilt and added to the group, we wouldn't need to add the listener then and update all of our apps/clients (i.e. that would force two migrations, one to the new server, one for the new listener).
I've tested this situation on a few test servers and its working as expected. I also can't foresee a reason not to do this, but I thought it would be worth the community ask since we're talking about Production DBs. My question is has anyone tried this and had any issues? Would anyone recommend against this solution. Thanks.
