When installing the Volume Activation role on Windows Server 2012 R2 and activating it with a Server 2012 Std/Datacenter KMS host key, would I still need to install the older product versions' keys (Server 2008 - Server 2012) to get the Vista+ and Server 2008+ instances activated?
The same question goes for Office 2013 - will an Office Pro Plus 2013 key activate Office Pro Plus 2010 as well?
Our "old" Server 2008R2-based KMS server which is due to be phased out is listing a plethora of keys as the output of
slmgr.vbs /dlv /all, most of them with
License Status: Unlicensed, but I simply do not know if this means they are never ever used again.
