Having been the person responsible for migrating data from an old system to a shiny new one, I wish I had read this a few years ago. However, since I will be embarking on rewrite from scratch project in a couple of weeks at a new position, I am glad I read this now. Migrating data is hard and should be given the same level of importance as the back-end or front-end development. I remember vividly the cycle of "sleeping" with my laptop next to me churning away over night, waking up every hour to check the process and having it fail at odd times. As the author said, make your migration process repeatable, testable and logged. Good luck.
