Let’s have a look at this article on how to use Active Directory Migration Server 2019 to 2022. In short, we will describe a way to innately migrate user profiles, databases, applications, shares, and data from any server to a new server in 2022/2019 with compatibility considerations and role migration best practices. In the previous article, I set up an additional domain controller on Server 2022.
