Hello media325,
Thanks for reaching out to us!
With Event Aggregator you can set up scheduled imports and when you set them up you can choose which events should be imported. I suggest to set up with a small set and see if that works out for you.
And of course, you can still use the legacy Facebook importer if you wish. Please note though, that our legacy importers are only receiving critical updates (if any needed) and only for a limited time.
Let me know if you have any more questions.
Cheers,
Andras
