Brakes are designed to open to the appropriate thickness of the rotors they are pinching, to account for wear. I didn't even need to reset the pads when I did the swap because my rotors were relatively new. I believe Shimano should be fine, despite using 1.8mm rotors, and Magura already uses 2.0 mm rotors so that won't be an issue.
