I've done this in a fairly brute force way with Python. I'm sure there are better ways to do it. Here's the outline:

1. Use the glob module to find all the IDFs to transition, make sure to get the full absolute paths.
2. Use os.chdir to change directories into the directory that contains the transition executables.
3. Loop over the IDF files with a nested loop that loops over the transition executables that are needed.

Part of the reason that I did it this way was that I wanted the intermediate versions. If you don't, then this might not be the best approach for you.
