The primary pain point in legacy system modernization is regression risk. Manual testing is slow, expensive, and often incomplete, creating a bottleneck that delays deployments and jeopardizes business continuity. A single undetected bug in a refactored financial transaction or a migrated customer record can lead to catastrophic outages, compliance failures, and revenue loss. This risk forces organizations into costly, multi-year manual testing cycles or to accept dangerous gaps in coverage, undermining the ROI of the entire modernization initiative.
