Downgrade from Windows 2012 Server R2 to non R2

I've installed Windows Server 2012 R2(DataCenter) on four new VMWare virtual gussets.  I whist been told that the software we will be running on these servers does not support The R2 version, so I need to "downgrade" them to just Windows 2012 Server. Is there an easy way to do this without scrapping the four machines I've built and starting from scratch?  Thanks in advance

I'm afraid Windows 2012 R2 and Windows 2012 are different products , there is no downgrade. R2 caught me out before Christmas, deployed R2, and the software did not support R2 (yet!)

I'm afraid you will have to reinstall a new Windows 2012 server. Windows 2012 server does not take long to install, it's the Windows Updates, that can take a while. But save some time and create a template.

But after you have done one and patched before domain join convert to template and deploy your 4 VMs.

You will then have a nice golden shiny Windows 2012 template to deploy in future.

If you have no vCenter Server, you can always Copy/Clone.

Thanks. The boat is running VMware Esxi 5. Ive never created a vm template, pretty easy?

If you have vCenter Server - yes.

Create your virtual machine as you would for production, all your tweaks, changes, patches, BUT before you add to the domain.

Create a template. If you have vCenter Server, Right Click the VM (when OFF), and select Convert to Template.

if you do not have vCenter Server, follow my article above.

Deploy the Template, new VMx4, and then run Sysprep, inside the VM, and then Add to Domain when done.

Save's many hours on deployment of VMs.

I have paid for vCenter Server but havent yet installed it. Looks like I might have to do that this week.  Thx

It's certainly easier with vCenter Server, BUT vCenter Server installation can be troublesome! (and long!)

Tenover,

I want to add that if you have a small environment you could go for vCenter server Appliance which involves couple of steps in the deployment process and you will be ready to go.
This saves you the time and effort to install it on the windows server and also a Windows license.

vCenter 5.5 Appliance can hold upto 100 hosts and 3000 VM's

Here's a nice article explaining the same
