Promote existing KMS client as KMS Host

Hi Folks,

have a situation, where I have to demote one of the DC(A) also holding KMS host role(for windows and office). but before that, looking to promote another DC(B) with KMS role.
Now that DC(B) is already a KMS client. so how would that conversion take place.

my understanding says below steps:-
1-)Installing volume activation role on DC(B)
2-)Install and activate KMS host key with slmgr.vbs on DC(B)  //fully understand the threshold of activation in order to get it operational
3-)Manually set SRV entries for DC(B) in DNS
4-)Uninstall KMS host key with slmgr.vbs on DC(A)
5-)Remove SRV entries for DC(A)

Please correct me if I am thinking wrong or If I need to follow steps in different way or anything?

P.S: DC(A) Operating system is WinServer2012 Std but have KMS Host keys until 2012R2 and office 2013.
DC(B) operating system is WinServer 2012R2 Std

From what you posted looks like the proper steps.

All KMS client look at DNS for the SRV and at that point the client registers.

So once you have the new KMS up and replaced your DNS SRV record the next time the client needs to renew it will renew against the new server.

Please note you need to get 5 servers and 25 workstations to register with the new server n a certain time frame.

By using the slmgr.vbs  -ATO on 5 of your servers to force renewal you will have a fully active KMS.

I would not remove the KMS role from the old server until you have a fully functioning new KMS.
