Hi, Anthony. Thanks for your interest in our plugin suite.
1)
Event Aggregator (EA) cannot import tickets from one site running Event Tickets (ET) to another.
2)
If you’re asking about importing from one site running The Events Calendar to another site running The Events Calendar, then you could choose to import that other site’s Event Category iCalendar feed.
Last but not least, we have a pretty great Refund Policy so you can buy one or many of our add-ons and thoroughly test them.
I hope this info helps. Let me know if you have any follow-up questions.
