Hi Mani,
Thanks for reaching out! You’ve got it right–any event or calendar shortcodes referenced in our Knowledgebase documentation are exclusive to our premium calendar plugin, Events Calendar PRO. If you’re already running the free version of The Events Calendar on your site, Events Calendar PRO will simply install right alongside this plugin, and all of your events and settings will remain intact. No need to work through a complicated transfer process; just install, activate, and go! 🙂
If you’re interested in learning more or in picking up a copy of Events Calendar PRO for yourself, you can get all the necessary info on our Events Calendar PRO product page:
https://theeventscalendar.com/product/wordpress-events-calendar-pro/
You’ll also find a link to our New User Primer under the Helpful Links heading further down on the page. I’d suggest bookmarking it for future reference, as it may prove helpful in setting up Events Calendar PRO and getting started quickly!
I hope that helps to get you on your way here! Thanks again, and please don’t hesitate to follow up if you should have any other questions!
