Migration vs. Upgrade:
Before we begin, it’s important to understand the difference between migration and upgrade. Migration refers to moving from one environment to another, while upgrade refers to updating the existing environment. Since Entra ID Connect is the same software as Azure AD Connect, there is no need to migrate if you are already using Azure AD Connect on Windows Server 2016 or newer. Instead, you can simply perform an in-place upgrade.
