Hi Sue,
Thanks for checking out Events Calendar Pro! The Pro version actually extends the functionality of the free version (instead of replacing it), so you will need to keep that active in order to use Pro.
There is no transferring at all of your events – event creation lives within the free version, and when you activate Pro, additional features (like recurring events) will be added to what you get in the free version.
If you’d like to test it out, we do offer full refunds within 30 days of purchase, so feel free to do so! Please let me know if you have any other questions.
Thanks,
Jennifer
