Fellow Microsoft MVP, Johan Arwidmark, has released his “Hydration Kit” for the new SCCM 2012 R2. What in the world is a “Hydration Kit” you ask? Simple! It is a series of scripts in Powershell, XML, and VBScript which will build out a complete SCCM 2012 R2 infrastructure, running on Windows Server 2012 R2 and SQL Server 2012 SP1, in either Hyper-V or VMware utilizing MDT 2013.
I typically use this to deploy a quick lab environment but you can also use this in production too. Please refer to this post and follow the step-by-step procedure.
