Executive Summary

Some of the world’s most critical operations still depend on software written before today’s engineers were born. At CN, one of North America’s leading transportation and logistics companies, that software processes about 10 million transactions and 55,000 waybills every day. Just one of their systems spans 17.4 million lines of code, much of it designed 40 years ago by engineers who are now retiring.

Gleb Geguine, Chief Enterprise Architect at CN, shares how CN is reverse-engineering its 40-year-old mainframe estate, combining software mapping and intelligence with AI to:

  • Map transaction flows and dependencies across millions of lines of code
  • Capture the ontology and system contracts that modernization depends on
  • Evaluate transcoding, mimicry and peel-off strategies based on estate realities
  • Modernize modules in parallel with ongoing discovery

Learn how you too can leverage AI with the right context to enable modernization at scale.
