Changing a projects target processor

Hi All,
I'm currently working on a project that uses a 16F876. I'm planning on changing the processor to an 18F2525 which is pin for pin compatible. What I'd like to know is, other than changing the device header to 18F2525.h are there any other considerations I should change to accomadate the new pic.

When I look inside the .PJT file I see there is an entry titled "Processor=0x876A". I guess this was created by the project wizard, but I can't see anywhere in the IDE where you can change/set the target processor. -Thanks

Somebody else will have to answer it. I don't have the PCWH IDE.

Open the file xxxxx.pjt using any text editor and change the lines

Processor_Text=PIC18F8722
Processor=0x8722

with the info for the new micro as well as changing the include file.

Thanks for the quick replies guys. I just changed the device header and the compiler took care of the rest. -Thanks
