From months to days, with $1M+ savings per refresh cycle.

The challenge

Sempra Energy faced a common enterprise dilemma: legacy infrastructure that could not keep pace with business requirements. Deployment cycles for new capabilities stretched to months. Public Utilities Commission requirements created compliance exposure that legacy systems struggled to address, while the cost of maintaining aging on-premises infrastructure climbed with every refresh cycle.

Our approach

BNS Networks partnered with Sempra to design and execute a migration strategy that balanced speed with the rigorous change management utility operations require. Workloads were prioritized by business criticality and regulatory exposure, so the highest-risk systems received attention first.

Each workload was assessed, migrated and verified before proceeding. Rollback procedures were documented and tested. The goal was not just to move to cloud; it was to move safely, with full operational continuity.
