Hello,
Thank you for posting in Q&A forum.
- About AD-based activation
AD-based activation allows you to automatically activate the Windows operating system in your domain through Active Directory. When you add a new host key to Active Directory, such as the Windows Server 2019 key you mentioned, this process creates a new activation object. Even if you add a new activation object, the original Windows Server 2016 activation object will generally remain the same, and the Windows Server 2016 instance that has already been activated should not be affected.
- How to activate Windows Server 2019
Add key: After you add a new Windows Server 2019 host key, you may need to use the following command on the newly installed Windows Server 2019 server to activate:
slmgr /ato
This will request activation and check if there is a valid activation object available in Active Directory.
Wait & Validate: Theoretically, computers in the domain will automatically activate when a new activation object is added. If there are any Windows Server 2019 servers that are not activated, you can manually run slmgr /ato to trigger activation. You can view the activation status in your environment by running the following command:
slmgr /dli
I hope the information above is helpful.
If you have any questions or concerns, please feel free to let us know.
Best regards,
