Can I write a P59 2004 GTO M6 operating system into a P59 2005 Silverado Allison ECU. Would I just do a write entire?

What is the Service Number and Hardware Number on the 05 box? 04 GTO is going to need a box that has IAC drivers in it. Not all 05 boxes will have them.
Mine has the IAC drivers. They just won?t work with my 8.1 DBW OS. I was just hoping to write a GTO OS over it to get the drivers to work.
