Is there any way to patch Hyper-V Server 2012 to Hyper-V Server 2012 R2? Or I need to download & install new version instead with manual VM migration?
I tried to google it, but found answers only about Windows Server 2012 with Hyper-V component.
Thanx.
Hyper-V Server 2012 and Hyper-V Server 2012 R2 are two distinctly different products. You cannot update from one to the other. You can upgrade from one to the other.
