Q. With different features in 2016 based on SKU are there features I lose moving from 2012 R2 to 2016?
A. No. While there are new features in 2016 only in the datacenter SKU which are focused on enterprise storage and networking scenarios, all features currently in Windows Server 2012 R2 standard will be there in Windows Server 2016 standard including, for example, Storage Spaces.
