I want to migrate our KMS from a Windows 7 to another server based on Windows Server 2012.
Volume Activation Tools is installed on that server.
When I enter my Win7 KMS key in the wizard of Volume Activation Tools, a message box shown:
This will uninstall the existing product key on the KMS host and install the one that you've entered.
Is that correct? Or, can I use Windows Server 2012 Volume Activation Tools to act as a KMS server to activate Windows 7?

Thanks for your reply. But that is not about my question.
I'm asking whether I can use Windows Server 2012 as a KMS server to activate Windows 7 or not.
Also, this server is a multitask one. I am worry about that message box.

do *not* attempt to install your Windows7 KMShost pkey upon Server2012!
the KMShost pkey must match the OS "family" of the machine you will use as the KMShost. (family = server, or client)
The KMShost pkey performs two functions:
a) it activates the OS of the KMShost itself (which is why it must match that OS)
b) it activates the KMShost behaviour of the KMShost machine
So, if you have a current KMShost, and that machine is running Windows7, it was activated as a KMShost using a Windows7 KMShost pkey.
Such a pkey is only acceptable on Windows7 OS. It cannot be used on a Server OS.
If you wish to use Server2012 as your KMShost, you must first obtain a KMShost pkey for Server2012 (from your MS VLSC website).
In such a case, your Windows7 KMShost and the Windows7 KMShost pkey upon that machine, both become redundant.
When a KMShost is running on a Server OS, it is able to issue activations for the same OS edition/versions and also down-level OS editions, and also down-version products.
e.g. a KMShost running on Server2012 issues activations for Windows8 + Windows7 + WindowsVista, also Server2012 + Server2008R2 + Server2008
