I have an instance of Windows Server 2012 running my website. This instance is 100% configured, with every single detail and fix I ever needed to perform. The problem is that now due to financial issues, we need to migrate to an instance with a lower configuration. I don't want to configure every little thing again. I didn't document my actions so I will run into some already fixed problems for sure.
I need to copy IIS, Firewall, WebDeploy, Windows features, and so on.
Is there any way in which I could copy my current instance's settings? Any Windows option or 3rd party software?
