Is there a script which will convert 40+ FM11 files to FM12, or do you have to do it one by one?
I'm not sure about a script step, but you can convert all your files at once by opening FileMaker 12, selecting File > Open, and Control or Command clicking the files you need to convert. You can then specify a location for the converted files to be saved to.
Doing them all at once is the best way. You can drag and drop the files onto the application icon.
