Primary/Secondary Controller

I previously purchased a Honeywell LYNX 5200 with zwave module to replace a pre-existing wireless security system while using all the the original sensors. It works great but I realized the automation functions are extremely limited. I’d like to set up more complex actions so I purchased a VeraEdge. Should be arriving today. My thought is to set the Edge or the LYNX up as primary controller and the other as the secondary. I’d still like to execute certain actions based on alarm arm/disarm conditions but want to take full advantage of the Edge’s more complex programming capabilities.

Did a search and found a little info but appreciate any recommendations you all might have on what the relationship should be between the two controllers.

Thanks!
