Upgrade Step for Windows AD Server to Windows Server 2019

Hi all,

I need your help as my situation below,

Primary server:

Windows 2008 R2 Standard (Master)

AD CS

AD DS

DNS

Secondary Server:

Windows 2012 R2 Standard

AD CS

AD DS

DNS

Replication AD only from Primary to Secondary server.

We have bought Windows Server 2019 Standard for two and we plan to upgrade both server,

I have found lots of step to upgrade AD server for easy ways by adding the bootable Windows iso media and run adprep /forestprep.

But I am worry If some thing else messup the configuration and AD itself.

My Plan,

1: Upgrade windows 2012 to Windows 2019

2: After all done, I will start upgrade Windows 2008 R2 to Windows 2012 R2

3. An then start to Upgrade to Windows 2019

Question : Any step or prerequisite before i start upgrading ? (for example, AD might not working during installation or etc)

Thanks

Ashraf

Windows 11 and Windows Server 2019/2022 ADMX Templates

Im making new GPO for Windows 11 but also server 2019 n 2022 based of CIS recommendations.

Now im at a point where I need to update the admx template files on my DC.

My questions is:

- Does windows 11 admx templates contain server 2019 n 2022 admx too? As i can find admx for server too but then that will overwrite for windows 11 right?

- What happens to existing GPOs when updating admx files, nothing right?

Thanks a lot
