Case Study: Leading Energy Company achieves 100% faster data processing and on-time cloud migration with Hitachi Vantara

Migration Solution Helps Energy Industry Leader Move to the Cloud

Leading Energy Company faced a forced and time‑boxed data center exit after a divestiture and acquisition, with legacy Windows 2003 servers, older SQL Server instances and batch/.NET apps and monthly penalties of up to $1M if delayed. To both meet the tight deadline and modernize its environment, the company engaged Hitachi Vantara and its Cloud Accelerator Platform to migrate and refactor its infrastructure to the cloud (AWS).

Hitachi Vantara implemented a rehost-and-refactor migration using its Cloud Accelerator Platform and AWS best practices (multiple AWS accounts, Well‑Architected Framework), running concurrent sprints, automated deployments and backups to ensure redundancy and integrity. The migration completed ahead of schedule with full production functionality retained, delivered a 100% increase in data processing speed, and delivered improved security, high availability, faster reporting and stronger disaster‑recovery capabilities.
