Hello Junie Johwa
You can perform an in-place upgrade from Windows Server 2016 directly to Windows Server 2022. Before starting, please ensure that your hardware meets the requirements for Windows Server 2022 and that all critical applications are compatible. It’s also strongly recommended to back up your system and test the upgrade in a non-production environment first. You can initiate the upgrade using Windows Server 2022 installation media and follow the guided steps provided in Microsoft’s documentation.
If this guidance helps, please don’t forget to hit “Accept Answer” 🙂.
