Converting to FIX 4.2

Imported from previous forum

Please point me to some information (e.g. white papers, lessons learned, etc.) regarding converting FIX versions, especially FIX 4.0 -> 4.2?

Thanks,
Steve

I gave a presentation at a conference in early 2001 about this exact topic, as well as conversion to FIXML. It’s available at this URL:
