We are currently running a server 2008 R2 KMS server that is being used to activate our Windows 7 and Server 2008/2008 R2 devices.

We are beginning to deploy more 2012 R2 servers and would like to use KMS to activate these as well. I have been doing a little bit of research online and it looks like we need to install a hotfix so 2008 R2 can activate new OS's.

After I install the hotfix is it as simple a task as running the

SLMGR.VBS /ipk {new 2012 R2 datacenter KMS host key}

From what I have seen it looks like the new KMS keys will work to activate down level clients. I just want to make sure this is the case before I replace the current key and mess up 2500 laptops and servers.
