Case Study: PMMC regains application knowledge and accelerates cloud modernization with CAST Imaging (CAST)

PMMC regains application knowledge and accelerates modernization for cloud

PMMC, a leading provider of revenue cycle management software and services for hospitals and health systems, needed to modernize and move five interlinked legacy applications to Microsoft Azure. The apps (C#, .NET, AngularJS, Dapper) share a SQL Server database and had been changed over years by teams no longer available, leaving no architect or up-to-date understanding of the as‑is architecture to guide the cloud migration.

PMMC deployed CAST Imaging and engaged CAST Professional Services to automatically reverse‑engineer the code into a living knowledge base with a map‑style web UI, creating a single source of truth. The interactive architecture blueprints let developers quickly visualize components and dependencies across UI, services, and data layers, accelerating onboarding and preparing the five business‑critical applications for modernization to Azure.
