[RM2K] MAP0001.IMU TRANSFER

I have an old game which uses the same maker version RM2K and would dearly love to use some of the Imu files in there which would save me some much time.
Is there a simple way to transfer them over I believe it has to do with matching up the file number but you have to be very CAREFUL indeed.
I of course would delete any Events or Teleport areas that would cause problems and are only interested in the graphic side of it.
Thank you kindly.

I'll give it go thanks.
