KACE published this article Windows 10 Build Upgrade Deployment Walkthrough (255380). That article is only supported by them if you are upgrading from ie Windows 10 1703 to 1809, but is not supported for upgrade from either Windows 7 or Windows 8.
The reason behind that is due to possible driver incompatibility. If a driver is not fully compatible with Windows 10 the upgrade will fail providing a warning.
Here is the command line to go around that:
setup.exe /auto upgrade /quiet /showoobe /quiet /compact ignorewarning
