Using A119 Mini 2 and A119M Pro in the same car

I currently have an A119 Mini 2 on the front windshield, but nothing on the back windshield. I'm considering upgrading to the A119M Pro and moving the A119 Mini 2 to the back. The GPS modules are identical, correct? So insteading of taking down the entire original set up, can I just switch out the actual dash cam? Will the app still work with two single-channel dash cams? Thank you.
