Setting up Volume License Service (KMS) on Windows Server 2012 R2

Good Morning!

We are attempting to stand up our own in-house reimaging solution. We have a Clonezilla server stood up, and have KMS Keys for the pieces of software we will be activating through the KMS Server (Windows 8.1 Pro 64-Bit, Windows 7 Professional 64-Bit, Office 2013 Professional Plus 32-Bit). However, I have hit a wall regarding the setup of our KMS Server.

We have a Windows Server 2012 Datacenter license. Because our organization is small, we operate entirely on VM Servers. These servers activate via the Datacenter key using MAK Activation. Some servers are on VMWare, while others are on Hyper-V.

I would like to install the VA Services role on the Domain Controller for our organization (It is a Hyper-V Virtual Server). However, this server has already been activated on the Datacenter MAK key. While setting up the Volume Activation Tools, it is asking for a KMS Host Key. Looking at the Microsoft TechNet, it appears that I need to input a Windows Server 2012 R2 KMS Key in order to continue setting up the Volume Activation Tools, and begin using the Volume Activation service.

I am squeamish, because I do not want the existing MAK key for the Domain Controller to be wiped out on the Domain Controller, or for the activation on this server to be affected. What I need to know is:

- Will we need to appropriate a separate Windows Server 2012 R2 KMS key in order to enable KMS on this server?
- Will any key entered into the Volume Activation Tools affect the key that exists on the host Server itself?

Sorry for the long question. I have been chasing this issue all week, and am just stuck. Thank you in advance for any assistance you can offer!

So, entering a Windows Server 2012 R2 KMS Key to activate Volume Activation Tools will wipe out the key on the Server that it is entered on? Just making sure I understand.  :)

Yes, it will replace a MAK, OEM, GLVK, or VMAK.
