try to update to a newer version of the tool.
That is obviously good advice, and is what I tried to do with our projects. Unfortunately file formats changed a lot, and the so called "Processor Expert Beans" are a particular problem.
We are using a Freescale DSP, not Coldfire but I suspect similar issues apply. Supposedly there is way to import projects from 4.7 to 6.3 then to latest Eclipse based version, but that garbled the project so much it was unusable.
Initially, I migrated projects by getting the 4.7 GUI up on one monitor, the CW10 GUI on another, and literally going through every tab of every window to migrate the bean settings, that took several days, the settings are not one to one. Compiling the source then does not produce an identical binary, since the compiler changes between versions. However tests on the target seemed to be correct.
After that I looked into the file formats, seeing as we have several projects to migrate. I discovered the file content was in fact very similar, but redefined as XML. I then spent a while writing a C# tool to read a CW4.7 project, and spit out a CW10 project, with only minimal cleanup required.
Then the remaining task was to persuade the other developers to leave their comfort zone and upgrade to CW10
