Case Study: Micron achieves 95% fewer downtime events and faster analytics with Snowflake

Migrating 500 TB of Data from a Legacy Data Warehouse to Snowflake

Micron, a Boise-based semiconductor manufacturer with over 37,000 employees, needed to modernize its legacy on‑premises data warehouse that was unstable, required a large IT and DBA team, and forced frequent, time-consuming infrastructure upgrades. The unreliable system caused prolonged downtime and degraded performance, limiting users’ ability to analyze manufacturing data and optimize processes.

Working with Snowflake Professional Services, Micron migrated roughly 5,000 tables and 500 TB of data — and hundreds of applications — to Snowflake in under four months. Snowflake’s separation of storage and compute, elastic scaling, and Time Travel snapshots simplified workload management, sped analytics (reducing a two‑week job to a few days), and enabled extensive testing. Post‑migration, Micron shifted 50% of DBAs to strategic work and cut downtime events by over 95%, empowering analysts and data scientists to apply ML to manufacturing data and drive yield and cost improvements.
