Hi Dario and thanks for getting in touch!
Yes, Event Aggregator is indeed the new service and we expect it will replace iCal Importer (as well as our Facebook Events plugin) over time.
The big difference here is that Event Aggregator is not a plugin but rather a service that is already included in The Events Calendar, which is a free download on WordPress.org.
Once you purchase a license and enter it into The Events Calendar, it unlocksĀ importing services for Facebook, Google Calendar, iCalendar, ICS files and Meetup.
iCal Importer, on the other hand, is only capable of importing from an iCalendar feed. It does not include the other options that come with Event Aggregator.
What about exporting events from the Event Calendar to Google Calendar?
Neither Event Aggregator nor iCal Importer were designed as tools to export events to other services — they’re for importing events into The Events Calendar. That said, The Events Calendar does include an iCal URL that can be used by Google Calendar to do a one-time fetch of events from The Events Calendar and import them into Google Calendar.
Does this help answer your question? Let me know!
Cheers,
Geoff
