First hands-on Upgrading to Windows Server 2022 Domain Controller #Windows2022 #Windows2016 #winserv #CloudOS #WIMVP
Windows Server 2022 is built on the strong foundation of Windows Server 2019 and brings many innovations on three key themes: security, Azure hybrid integration and management, and application platform. Also, Windows Server 2022 Datacenter: Azure Edition helps you use the benefits of cloud to keep your VMs up to date while minimizing downtime.
As some of my Domain controllers are running on Server 2016 this is a great moment to upgrade them,Upgrading a domain controller is always tricky when you loos you AD, well I got a copy in Azure 
How ever Windows Server 2016 is supporting Rolling Upgrades Upgrading to Windows Server 2022 but this is only for a Cluster.
For other Servers you can upgrade your server or better reinstall. Bet you all choose for the Clean install. Well For a domain controller, it’s a quick process to redeploy but often there is ton’s of software on the DC that should not be there and makes it hard to loos the DC right ?
So my DC server 2016
Finding the FSMO roles
netdom query fsmo
You can’t upgrade the server when there is a FSMO role running on the server. Tested this and if failed So move the FSMO roles from your DC.
Yes I hear you you have only one DC well create a virtual second one and move the fsmo roles to that server upgrade and move the roles back and demote the Extra DC and you are back to a single DC.
my other DC is mvpdc22
I move the roles to my second DC
Quick and Smooth migration
Move-ADDirectoryServerOperationMasterRole -Identity “Your-DC” -OperationMasterRole SchemaMaster,RIDMaster,InfrastructureMaster,DomainNamingMaster,PDCEmulator
I mounted the ISO to the DC (virtual CD disk)
YEs I want to make the product better.
Use your Product key or if you are on hyber-v you can use the AVMA key https://docs.microsoft.com/en-us/windows-server/get-started-19/vm-activation-19?WT.mc_id=AZ-MVP-4025011
The following AVMA keys can be used for Windows Server 2022:
Datacenter
W3GNR-8DDXR-2TFRP-H8P33-DV9BG
Standard
YDFWN-MJ9JR-3DYRK-FXXRW-78VHK
I still love my gui So I install the desktop experience
Read the entire EULA and I agree.
My domain Controller desktop (remember this is my lab) Don’t use your DC for any other things than using it for a DC.
I want to keep My files
Yes Install
Let the Setup running
So in just 20 min my DC was upgraded to 2022 lot’s of new stuff is there but that’s all for a next blog post. Hope it was usefull and remember make sure you have a backup things my fail in your environment
