Reimagining legacy applications with Pega and AWS through AI-driven approach

AWS Partner Network Blog



This article describes the AI-Driven App Modernization Platform from Pega and AWS, which transforms legacy applications into intelligent, automated workflows through a structured three-phase methodology.

  • Phase 1 uses AWS Transform and Kiro to reverse-engineer legacy systems (COBOL, Java, .NET, ERPs) into structured business functions and requirements
  • Phase 2 employs agentic AI via Pega Blueprint Agent to design modernized applications with case management and decisioning capabilities
  • Phase 3 deploys applications incrementally using the strangler fig pattern, routing traffic between legacy and new systems without disruption
  • Supports mainframe systems, legacy BPM platforms, Java/.NET applications, document workflows, ERP transformation, and application consolidation
  • Anti-corruption layer protects new Pega applications from legacy complexity through REST API integration
  • Benefits include accelerated timelines, reduced risk, lower TCO, improved business agility, and enhanced user experience

The platform enables organizations to reimagine legacy processes on a cloud-native, agentic platform designed for the AI era while maintaining business continuity.
