I have an existing installation of TFS 2013 with an app server and a DB server. I would like to add a second DB server and set up SQL Always On availability groups? I see articles about creating this setup when you first install. I haven't found instructions for the scenario where you add it after you TFS system is running.
My configuration:
TFS 2013
SQL Server 2014
SharePoint 2013
SQL Reporting services running on the app server with the database on the DB server
