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.
