The system that was originally the domain control server in my company was windows server2008R2. This year I migrated the domain control to the Windows 2022 server, and it ran normally.

Now I need to downgrade this Windows Server 2008R2 domain controller. I have seen this tutorial,

How to migrate Active Directory from Windows Server 2008 R2 to Windows Server 2022 (microsoft.com).

But managers believe that official documents are needed, such as:Demoting Domain Controllers and Domains (Level 200) | Microsoft Learn

But this is not about Windows Server 2008R2. I have been looking for it for a long time but couldn't find it. So I come here to ask for help. Thank you.

    Hello,

    Thank you for posting in Q&A forum.

    I understand your need to seek official Microsoft documentation.

    Unfortunately, Microsoft has ended support for Windows Server 2008 R2 and much of the official documentation related to it has been archived or removed.

    Also, the process of demoting a domain controller is usually similar in different versions of Windows Server. You can try to follow this document to downgrade your domain controller.

    Demoting Domain Controllers and Domains (Level 200) | Microsoft Learn

    Please don't forget to back up all your important data before downgrading.

    I hope the information above is helpful.

    Best Regards,

    Yanhong Liu
