This article will help you how to upgrade Server 2016 to 2022. If you wish to keep the same hardware and all your server roles you have already set up without demolishing the server, you will need to do an in-place upgrade. In-place upgrades allow you to go from an older operating system to a new operating system while keeping server roles, settings, and data intact.
Before you Start in-Place Upgrade

Because this information is aimed for use only if the upgrade fails. You should make sure that you saved the information someplace that you can get to it off of your device.
Before starting to upgrade, have an Overview of Windows Server upgrades.
How to Collect System Info
Run a command prompt with admin rights, go to C:\Windows\system32, and then enter systeminfo.exe. Please store the resulting system information someplace off of your device.
Enter ipconfig /all into the CMD let, and then saved the resulting configuration information into the same place as above.
Verify Server Build Version
