Hello,
I'm planning to patch my SharePoint "Test" farm. Before doing so, I want to detach the "Test" content DBs from the "Test" web application and attach the "Prod" content DBs to the "Test" web application. The purpose of this is so I can have an idea of high long the patching process will take on a Production Farm. I have taken a backup of the Prod content DBs and copied them to the "Test" DB server. The "Test" content DBs still exists. My original thought was to attach the Prod DBs to the web application, perform the patch then detach the Prod content DBs and attach the "Test" content DBs backed to the "Test" web application. Will doing so, cause issues with the SharePoint farm?
