Uninstall Dongle license and Re-install new, non Dongle license

Hi all

What’s the best way to uninstall a V-Ray Dongle license from a mac and then to reinstall a newly purchased, non Dongle license?

The Dongle license wont be used in the office any more, and we’re purchasing a new monthly license (which I assume is now a Dongle free license type?)

Cheers

Cool, cheers.
