Platform File Data Migration

The challenge

A major feature release required restructuring chunk, file, and embedding data inside a live production database — the entire data set of a 7,500-person company, 65,000 user files and roughly 3 million chunk and metadata records — without losing data or degrading the product for the people using it.

What we built

We ran a phased migration across the platform’s document store and object storage over two weeks, altering fields in careful stages so no user data broke, with dedicated cloud compute scaled up to process the volume. The migration was AI-driven end to end and coordinated across teams, and cost only a single weekend of database downtime with zero degradation of the user experience. The backup and disaster recovery strategy we built as its safety net remains in use at the company.
