Chime Box Wiring

I recently upgraded from a Pro Model to a Pro 2 model which was straight forward, I would like to redeploy the older pro model and replace an existing Video doorbell wired, In the chime box I have the power kit on the transformer and front door terminal and a wire from the transformer to the same front terminal for the Video Doorbell wired model. Question, do I need a second power kit in the chime box and or do I remove the wired connection between the transformer and front terminal. Does a single power kit handle the power requirements for a pro 2 and pro model connected to the same chime box?
