Global Benefits Provider

A global workplace benefits and insurance provider supporting more than 30 million employees faced a critical platform challenge as its MongoDB 6 database approached end-of-life. With over 70 interdependent repositories, no automated QA suite, and systems embedded across multiple product lines, the organization needed to modernize its technology stack without risking stability or downtime. gravity9 was engaged to address this high-stakes upgrade, working under strict timelines to ensure that new versions of Java, Spring Boot, and MongoDB behaved identically to the legacy environment while coordinating testing across numerous internal teams and ongoing workstreams.

gravity9 delivered a zero-downtime upgrade by designing a parallel environment strategy that allowed old and new systems to run side-by-side, enabling clean comparison, early issue detection, and minimal disruption. The team modernized the full application stack, upgraded the production MongoDB cluster to version 8, and supported every deployment cycle across lower environments to guarantee consistent outcomes. The result was a fully supported, future-proof platform with improved performance visibility, reduced operational risk, and a modern foundation ready for the next generation of features—achieved without a single post-deployment incident.
