Without knowing things such as:
What is under the old metal
What type and configuration the old metal panels are
What type and configuration the new product will be
...
I would suggest removing the old and then making sure that what you're going over is in keeping with the metal roofing manufacturer's instruction.
Please feel free to contact me if you would like to discuss this further.
