compatibility: Domain controller window2019 & windows2022Domain controller

Question

Hello Team,

I have Primary Domain controller which is running on windows server 2019.
Now need to create a backup/secondary Domain controller with window server 2022.

Question:

Does it sync both servers ( DNS,DFS,AD,GPO ,etc) ? or do we have any compatibility issue .

If any have idea on this scenario kindly share the Microsoft document(link)

Hello Bhanu Singh,

Thank you for posting in Q&A forum.

It is entirely feasible to run a primary domain controller on Windows Server 2019 and intend to deploy a backup/secondary domain controller on Windows Server 2022.

Windows Server 2022 as a domain controller has good backward compatibility with Windows Server 2019. They can work together seamlessly in a domain environment, synchronizing DNS, DFS (Distributed File System), AD (Active Directory) and Key components such as GPO (Group Policy Object).

Once configured, all changes to Active Directory are automatically replicated between the primary and secondary domain controllers, maintaining data consistency. Changes to all AD components such as DNS records, Group Policy Objects (GPOs), user accounts, security policies, Distributed File System (DFS) settings, etc. are automatically replicated across all domain controllers.

Please refer to the link: How to Install Additional Domain Controller Server 2022 - XpertsTec

I hope the information above is helpful.

Best Regards,

Yanhong Liu
