So I am working on a customer and their path of upgrading to 2016 versions. The first step was to make sure that the VMM 2012 R2 server was updated to latest UR and that I can deploy guest vm´s with 2016.

After the update of VMM to UR11 I checked the list of OS,

So to be able to see the 2016 as a guest OS i have to add a hotfix and that took some time but what ever you do, do not cancel but wait and wait and wait and the never ending progress bar will eventually go away 😉 . And yes you have to add one hotfix for the console and one for the vmm server!

And once that is applied,

Good luck in your upgrading story !
