Vera Edge communicating with alarm system NetworX NX-6V2 (Arm, disarm, trigger)

I am not sure where to post this question.
Want to arming, disarm, monitor alarm system via my mobile phone

Looking for best economical path I should take to have my current alarm system (NetworX NX-6V2) talk to my (Z-wave controller) Vera Edge?

What modules do I need to work with my current system NX-6V2 to communicate to my Z-wave Vera controller.

Or should I upgrade to “Interlogix NX-8”, what modules will I need for this main board to talk to my Z-wave Vera controller. Also will it fit in my NX-6V2 cabinet. ???
