How to Migrate Active Directory Server 2012 to 2022
This article will help you to migrate active directory server 2012 to 2022. If you wish to keep the same hardware and the server roles you have already set up without leveling the Windows server, you will have to do an in-place upgrade. In-place upgrades allow us to go from an older operating system to a new one while keeping your settings, server roles, & data thorough.
I am writing this article, to help Windows admin migrate an existing Active Directory which is working on Windows Server 2012 R2 name (DC2012) to Windows Server 2020 name (DC2022). So, let’s get started.
Please visit Microsoft Website for Upgrade Overview
This is a very straightforward procedure, but first, you need to test it in your Test Environment.
In my test lab, I have two Servers and my local domain Server is (xpertstec.local).
| Virtual Machine | OS | Role | IP Address |
| DC2012 | 2012 R2 | Primary Domain Controller | 192.168.241.150 |
| DC2022 | 2022 | Secondary Domain Controller | 192.168.241.160 |
