AS400 Modernization in Healthcare Supply Chain with Legacy Support
Project Overview
A major logistics distributor headquartered on the U.S. East Coast—serving dental, pharmaceutical, and healthcare-related products—relies on a legacy AS400-based Warehouse Control System at the core of its operations. Over the last 12+ years, United Techno has been a trusted partner in managing, maintaining, and modernizing the customer’s legacy systems while supporting its transition to a hybrid IT landscape powered by SAP, Oracle OTM, Snowflake, and robotic automation.
