Here we are in part three of the Q&A series, where I’m working through the multitude of questions that were asked during the recent ‘What’s new in Windows Server 2016 Preview’ JumpStart course, which, if you haven’t heard, is now available on-demand, so check it out! In this post, I’ll be walking through the questions focused around upgrading to Windows Server 2016, specifically using the new rolling upgrade capabilities, then wrapping up with some questions under the banner of ‘Operational Efficiencies’, which, between you and I, are a load of cool and handy features that just make life better for the Hyper-V admin. Here we go…
Can you upgrade from Windows Server 2012 to Windows Server 2016 or only from Windows Server 2012 R2?
No, as detailed on TechNet, this feature only works for clusters transitioning from Windows Server 2012 R2, to Windows Server 2016. Any earlier editions of Windows Server would have to be upgraded to Windows Server 2012 R2, before you could take advantage of the rolling upgrade. There are no plans to port this feature back to previous versions of Windows Server.
