Hi Sanket,
Thanks for reaching out!
Event Aggregator will let you schedule imports from one site using The Events Calendar to another site using The Events Calendar, so this might be a good option for you – no customization required!
You can also take a look at our out-of-the-box export functionality that comes with Events Calendar Pro.
As far as a customization, this would be outside the scope of support that we are able to provide in our premium support forums, and we are not able to provide any technical support here in our Pre-Sales forum, which we use to answer questions on our premium plugins for those interested in purchasing them. If you’d like to give the customization a shot, our themer’s guide is the place to start.
We do offer full refunds within 30 days of purchase, so if you’d like to take Event Aggregator or Events Calendar Pro for a test run, feel free to do so! Please let me know if you have any additional questions.
Thanks,
Jennifer
