How to keep WordPress Popup settings when upgrading to Popup Pro?

How do we upgrade to Pro from https://wordpress.org/plugins/wordpress-popup/ ? We are already WPMUdev subscribers and possess Pro - https://premium.wpmudev.org/project/the-pop-over-plugin/

My developer accidentally started using the free version and did not realize we already had access to Pro, so she did work with the free version that we do not want to lose.
