Surviving Database Migrations: Ambitious and a little crazy

May 27-29, 2026 • Computer History Museum, CaliforniaDate, time, and room will be announced soon.
Learn how we survived a 2.5 year database replatforming at Plaid where we moved 234 databases across 100 services. How did we survive and how should you approach it when you face an impossible task that’s a “default fail” scenario?
We’ll dive deep on the factors that helped us succeed:
- From a critical assessment of business constraints
- Making things better every time
- Cross-functional alignment
- Building the dream in flight
- Front-loading risks
- Building a championship team
After hearing this talk, you’ll be able to give informed consent when subjecting your team to the grueling challenge of rebuilding a data-platform in-flight. It’s everything I wish I knew when I started out that fits into thirty minutes! Buckle up and turn off your pagerduty because this will be a whirlwind.
