VeraLite 1.5.622 to VeraPlus, do I have to upgrade the VeraLite to UI7

@Sorin is this still the case? I am having serious issues with my plus that lenard was not able to connect to it. This all started after firmware update and because of this Vera is sending me a new Plus and I need to move system and z wave network over to the new unit when it arrives. I have two door locks that are battery powered! (the node ID change you addressed in one of the replies)
