In 2016, Dropbox migrated over 600 petabytes of data from managed cloud storage into its own data centers. This effort, which involved over 100 people, required extreme levels of coordination and a focus on detail.

Andrew Fong shares lessons and best practices for data migrations learned from this experience. You’ll learn about how to plan migrations, durability and verification, and how to prevent burnout of the team during such events.
