Performing an In Place upgrade from 2012 to 2012 R2

My host (Windows 2012) was running 1 virtual machine.

pre upgrade

I doubled clicked the iso to mount it, ran the setup, then selected install.  I received no warning telling me to power off my VM.

installThen selected No Thanks to downloading updates,

Capture2I then selected a GUI install

Capture3I then Accepted the terms and selected next,

Capture4I then Selected upgrade,

Capture5The install took slightly longer than 10 minutes.  Once the install had finished and I logged in, the machine was on the domain, all roles and features were installed as expected, Hyper-V was fine.  I powered on my Virtual DC.  The DC powered on fine and there were no issues at all.  This was a very painless operation with minimal downtime.


Can’t attach existing VHD to a new Virtual Machine?

Can’t attach existing generation 1 VHD to a new Virtual Machine? Hyper-v 2012 R2 will not let you add a W2k8r2 vhd to a generation 2 Virtual Machine.  It must still be a generation 1 Virtual Machine.

If your existing generation 1 VHD is Windows 2012 it will let you create a VM that is generation 2.  When you go to turn it on it will power on, but not boot correctly.

Hyper-V 2012 R2 can not be tricked and this will not work..
