Wyse Converter for PCs

Hi,

Do I need WMS Pro instance for manage converted Wyse 5470 with Windows 10 OS? Is that possible to manually convert terminals, and manage them by WMS Standard (free) version?

Is that any other possibility to convert Wyse 5470 from Windows 10 -> Windows 10 IoT? Can I buy an additional licence for that (Windows 10 IoT license).
