Windows Server 2016 Datacenter activation

We acquired a license for Windows Server 2019 Datacenter but we need to install Windows Server 2016 Datacenter. What is the procedure to convert the Product Key for activation?

 

Where can I find the patches for datacenter edtion windows server?

Hi MS support,
I have received security alert from my company's Cyber team, said Remote Code Execution Vulnerability detected in my Windows server 2019/2016 datacenter Edtion, I found solution at Security Update Guide - Microsoft Security Response Center
the link has all the versions EXCEPT Datacenter ones. I have tried to install the patch Windows server 2016/2019(not Datacenter edtion), which is not applicable and not able to install.

So please guide me to find the patch for Windows server 2019/2016 datacenter Edtion.
Thanks,
Luome
