I got a DE2 board that failed so they sent me a replacement board which is the finer DE2-115. But my config file (.sof) is not forward compatible. How can I migrate existing projects that I have for the DE2 to DE2-115? I think I need to define a .sof file and I don't know how to do that, it was my university instructor who gave me a public domain .sof file that works with the DE2 but not the DE2-115. I got a spec error msg saying something like pins are different from the Quartus envirronment. Can you propose or suggest what I should do?

I got C code, assembly and hardware definitions that work with the DE2 already. So I want these in DE2-115 as well instead of getting started from scratch with DE2-115 I just want to move some projects but the .sof file is incompatible beteween DE2 and DE2-115. The big difference is that DE2 uses Cyclone II while DE2-115 has Cyclone IV chip.
