I have an existing IDA Pro project for a C166 processor embedded application. This project already has many functions, variables, etc defined.

There are different versions of the embedded application I am looking at. The different versions of the application are 99% the same, but with slight variations in code and data that cause functions and variables to be at different memory offsets.

I want to create a new IDA project for a different version of the application. I would like to somehow import all of my function and variable definitions from my existing IDA project.

I would like IDA to recognize the signatures of the existing function definitions and define them at there new location in the new project.

How can I do this? Are there certain plugins for IDA I can chain together?
