What we are using to report on Win7 to Win10 migrations is the validate dashboards.
Stacked menu then Validate - Configuration Change - 1 pick OS Name Change - 2. change to Windows 10 - 3 Pick any date.
This will give you a before after comparison for many data points. You will want to make some additional changes to the dashboard to get what you want and you may also want to create a pilot group for this device.
Hope this helps!
