If the CPU part numbers are exactly the same, you should have no problem simply inserting the MMC in your second CPU, provided that the firmware version in the second CPU is the same or newer than the first CPU.

If you put the MMC in the new CPU, it will have the same program, because it is stored on the MMC, and the Data Block values (DB) will be with their initial values.

So all I should do to put mmc in New cpu and power on then run is that what u mean thank you

Yes, just be aware that the DB values will be as they were when they were downloaded to the CPU.

Which has it's benefits if there are a million PID loops and other variables....
