As organizations increasingly leverage the Databricks Data Intelligence Platform for data and AI needs, upgrading to Unity Catalog is a key step in enhancing discovery, governance and security to unlock the platform’s full potential. UCX, a powerful tool developed by Databricks Labs, simplifies this transition by automating the upgrade process, ensuring a smoother and more efficient journey. In this blog, we’ll show how UCX can be a powerful companion as you plan your upgrade journey to Unity Catalog.
What is UCX?
UCX is an open source Databricks Labs project designed to assist organizations in upgrading their non-Unity Catalog workspaces to Unity Catalog. Developed by a team of experienced Databricks experts including field engineers who understand the intricacies of such upgrades firsthand, UCX stands as an essential tool for organizations undertaking this transition. This comprehensive toolkit offers a range of automated workflows to address various aspects of the upgrade process, including:
- Assessment of workspace compatibility with Unity Catalog
- Migration of group identities and permissions
- Upgrade of Hive metastore tables to Unity Catalog
- Code migration and data reconciliation
UCX is particularly useful for organizations with large amounts of data in their Hive metastore and complex workspace configurations. It offers both command-line utilities and visual interfaces to cater to different user preferences and use cases.
Why upgrade from Hive Metastore to Unity Catalog?
While Hive has served as a reliable metadata and data management solution for many organizations, its limitations in handling diverse, modern data and AI workloads can hinder agility, governance, and collaboration. Unity Catalog addresses these challenges by providing the industry’s only unified, open governance solution, purpose-built for managing all data and AI assets. As the cornerstone of a modern data intelligence strategy, Unity Catalog integrates the power of Lakehouse and AI, enabling a comprehensive understanding of data while delivering contextual, domain-specific insights that boost productivity for both technical and business users.
Built on an open source foundation, Unity Catalog supports seamless discovery, access, and sharing of trusted data and AI assets across any tool, compute engine, or cloud platform. This unified and open approach encourages cross-functional collaboration, accelerates data and AI initiatives, and simplifies compliance—allowing organizations to keep pace with an evolving data landscape while unlocking the full potential of their data investments. Over 10,000+ enterprises are now leveraging Unity Catalog to govern their data and AI estate.
