Case Study

When Legacy Infrastructure Becomes a Growth Bottleneck

The existing mainframe environment was failing to support the rapid scaling of dealer networks and complex inventory demands.

The organization needed modernization — without downtime.

Monolithic Architecture

Slow innovation cycles and rigid integrations limited the ability to launch new dealer features.

Massive DB2 Volumes

Migrating terabytes of records without downtime posed an extreme risk of data corruption.

Outdated Green Screens

Low adoption and inefficient workflows led to manual errors in vehicle processing.

API Orchestration

Significant real-time inventory sync between legacy systems and modern sales tools.

System Evolution

Legacy vs. Modern

A side-by-side view of the radical transformation in infrastructure and processing capabilities.
