Upgrade VeraLite to UI7?

Should I decide to get a VeraEdge or VeraPlus should I upgrade my VerLite to UI7 now?

Also, is PLEG and HomeWave upto date for UI7?

Upgraded my VeraLite to UI7. Running great!!! I just updated firmware to 1.7.730 and everything is still great but it loaded a group of motion sensors under Devices. I can’t delete the motion sensors from my Devices. Oh well, still running great!
