Haptics Instruments vs Vibration Port

Hi there. I’m starting to work with Haptics for the first time and got a bit confused with what’s in the documentation.

I understand Haptics Instruments are a new addition (I believe on 2.03.11), but is it supposed to replace the Vibration Port workflow?

Are they 2 different ways to add haptics to a game, or should I route an event containing a haptics instrument to the vibration port?

Hopefully I was clear enough with my question! Cheers.
