Newbie Question: How do I modify PIC24F demo to run on PIC24FJ256GB210?

I successfully compiled the PIC24_MPLAB demo for PIC24FJ128GA010 but need to get it to compile and run on a PIC24F256GB210. Looking for some tips.
Thanks in advance

Are there any differences in the PIC24 core between the two parts? If not, you should not need to do anything other than update the linker file so it describes the additional memory correctly.

You can use Harmony code generator to generate a project for your part and then use the linker script from that generated project.
