How to migratie an Windows Server 2008 R2 KMS to Windows Server 2012 R2, for volume activation of Microsoft products? On a new KMS server? You don’t, apparently there is no Windows Server 2008 (R2) KMS to Windows Server 2012 R2 migration. There is no way to automatically transfer your KMS role along with the products its activating to another server. Luckily Charity Shelbourne wrote up a handy how to for this task.

Let’s get a few things straight.
THERE IS NO MIGRATION.
There is no way to automatically transfer your KMS role along with the products its activating to another server.
But don’t panic.
THIS IS NOT A BIG DEAL.
Your organization is not going to go up in smoke if your KMS host is unavailable for a short period of time.
It’s not mission critical.
But it is necessary (unless you’re on Windows 8/Windows Server 2012 and later and Office 2013 and later and can use Active Directory Based Activation).
So what’s the answer then?
You build a new one.
If you are prepared, the process takes all of 5 minutes, 30 minutes max. Yes, it really is that easy.
You don’t need to worry about your KMS count (remember we need a count of 25 for Windows servers/clients and a count of 5 for Office clients before we’ll activate). Your KMS count will increase almost immediately when KMS clients renew their activations and find your new KMS host or if you can force it by using VAMT, multi-selecting a bunch of clients, and tell them to activate in which case they’ll immediately go and renew their activation interval with the new KMS host.

How-to verify your (new) KMS host address #
You can verify your new KMS host address on the cmd.exe command-line in Windows, using
On one of your clients, execute the following
nslookup lookup to verify your newly created KMS host address in DNS:
nslookup -type=srv _vlmcs._tcp.[active directory domain].
Verify successful Windows activation #
Verify everything activated successfully by running the following command from an administrative command prompt:
Cscript C:\Windows\System32\slmgr.vbs /dlv All
