    By Heather Williams

  2. The Problem • A large codebase • Around 3 000

    python files used to generate questions on a website • Monolith disguised as microservices

  3. Solution: Walled gardens • Make the monolith a true monolith

    • Identify the real microservices • Docker all the things • Walled garden around the python files for questions

  4. Solution: automate it Python 2to3 is a great tool https://docs.python.org/3.0/library/2to3.html

  5. Solution: requirements files • Remove unnecessary dependencies • Upgrade out

    of date dependencies • Note what needs python 3 to upgrade

  6. Great snakes migration Take the plunge and do it!
