Everything will work out just fine.
One piece of advice:
Keep your Mavic Pro because this model can fly true autonomous missions.
ALL newer drones, starting with the Mini-1, that use the DJI Fly App, use VSC (Virtual Stick Commands) to fly waypoint missions which doesn’t result in footage as smooth as with your drone, AND needs a constant and good quality connection between the drone and remote. Your drone can finish a waypoint mission even with the controller turned off.
