Not really if you write the code the right way.  My PIC development
environment (http://www.embedinc.com/pic) makes it easy to write code that
transfers easily between PICs, especially if they have the same core as the
two you are talking about do.

To change a working project to another PIC:

1  -  Change the processor selection, oscillator frequency, and possibly the
software stack location and size in the xxxLIB.INS.ASPIC file.

2  -  Change the config bit settings in the SRTS module.

3  -  Change the linker file to that of the target PIC.

4  -  Possibly change the /INBIT and /OUTBIT I/O bit declarations in the
xxx.INS.ASPIC file if you need to use different port pins between the two
PICs.

If you've done everything else right, there should be no changes required in
the executable code.
