Hi John!
Thanks for getting in touch with us!
We apologize for a bit of delay in getting back to you. We are dealing with a high volume of threads at the moment and we are slowly getting back to normal response times.
We have an export events functionality you can learn more about in the following article > https://theeventscalendar.com/knowledgebase/exporting-events/. However, there is no built-in functionality to migrate events from one site to another.
There are various ways you can achieve that. You can use the WordPress built-in export-import tools by navigating to your WP Admin > Tools > Export/Import.
Another way is to export your events using a third party plugin like WP All Export, which will let you export your events (and other post types as well) to a CSV. It also lets you choose which fields you would like to include in the export. Then you can use our Event Aggregator tool to import the events, venues and organizers from the CSV file.
I hope that helps. Let me know if any follow up questions.
Best,
Victor
