Databricks → Snowflake Migration

As part of a transition from a centralized data lake to a data mesh architecture, Sanofi needed to migrate several critical data domains — including data science workloads — from Databricks to Snowflake. The migration had to be executed without disrupting existing business processes while enabling teams to adopt modern data warehousing best practices.

OrbitaLab led and executed a controlled migration from Databricks to Snowflake: Re-architected data structures to align with Snowflake’s analytical and data mesh principles Migrated critical data domains and data science infrastructure with minimal operational disruption Ensured continuity of existing workloads during the transition Actively involved internal teams throughout the migration process Delivered hands-on knowledge transfer and training to enable long-term self-sufficiency and adoption of industry best practices
