The licensing rules that actually matter here.
GetGenuine licenses legalize existing installs that never had a proper license; Pro upgrades require a qualifying base license on the device.
One license per device, perpetual. If devices are Entra-joined and under Intune, a Microsoft 365 subscription may already cover the upgrade — ask before buying.
