Before Running upgrade check for license conversion options as well. Not all upgrades support license conversion.

Note: Upgrades that switch from a Server Core installation to a Server with a Desktop installation (or vice versa) are not supported. If the older operating system you are upgrading or converting is a Server Core installation, the result will still be a Server Core installation of the newer operating system.

Note: – Before running upgrade make sure hardware and running applications support new version of windows. I will recommend to run upgrade in test environment first.
