Retiring a decade-old legacy core
A regional enterprise needed to modernize a legacy core system without halting operations. A phased migration plan moved critical services over in six low-risk stages.
The legacy core had become a bottleneck for new product work. Previous modernization attempts stalled because the business could not afford downtime or failed migrations.
We designed a six-stage migration plan that moved services incrementally, with rollback paths and parallel validation at each phase.
Production incidents dropped 40% after migration, and the team gained confidence to ship new features on the modernized platform.
