Reimagine mainframe applications for AI-readiness

AWS Transform for mainframe is an agentic AI service that reimagines mainframe applications into AI-ready, cloud-native systems, compressing multi-year modernization timelines into months. The service delivers the full modernization lifecycle from assessment and business rule extraction through requirement generation, with traceability embedded at every step. From there, customers leverage coding agents like Kiro to build modern applications, complete microservices, and production-ready code.

Benefits

Full lifecycle modernization where every output traces back through requirements to the original source code.

Teams start with a prioritized modernization plan and clear business case before any code is written. From there, agentic AI automates transformation workflows in parallel across workloads, compressing what previously took years of sequential effort into months of concurrent execution.

Every line of generated code traces back through requirements to the original source code it replaces, creating a complete audit trail from modern to original. Business rules are extracted, verified, and transformed into traceable requirements so teams can prove functional equivalence at every step. This embedded traceability gives teams the confidence that nothing was lost or invented during modernization.

AWS Transform integrates with existing development environments, CI/CD pipelines, and partner delivery models through open protocols including MCP. Teams connect their preferred IDEs, testing frameworks, and agents without changing established workflows. Partners build differentiated practices on top of the service, extending their existing delivery methodologies.

Core systems trapped on the mainframe cannot participate in the agentic era. Modernized applications expose your most valuable business logic and data to AI agents, Amazon Bedrock, and the full AWS AI/ML stack. Claims, payments, fraud, and compliance workflows gain access to generative AI and real-time decisioning that mainframe architectures can't support.

Reimagine mainframe applications step by step

AWS Transform for mainframe uses agentic AI to guide your modernization from initial assessment through production deployment. Each step produces verified, traceable outputs, so your team maintains confidence throughout the journey.

Assess your mainframe estate and select workloads

AWS Transform for mainframe analyzes your entire codebase to surface dependencies, complexity metrics, and workload boundaries. The assessment recommends which workload to start with and generates a prioritized plan, giving your team a clear starting point based on business value, not guesswork.

Extract business rules into traceable requirements

Every business rule is extracted from your source code and traced to its origin. AWS Transform for mainframe then generates development-ready requirements that your team can review, each traceable back to the source code it originated from, so nothing is lost or assumed before transformation begins.

Generate code you can trace back to the source

AWS Transform for mainframe reimagines your applications into cloud-native architectures where every output traces back through requirements to the original source. Every output links back to the original rule it came from, giving your team an auditable chain from original to modern. End-to-end integration with Kiro connects requirements directly to your development environment.

Validate functional equivalence automatically

Automated testing validates that every reimagined application behaves identically to the original. AWS Transform for mainframe generates test plans, creates test data, and executes validation scripts so your team can verify functional equivalence, minimizing manual effort.

Move to production with confidence

AWS Transform for mainframe generates deployment-ready artifacts including infrastructure-as-code templates and environment configurations. Your team gets a clear path from transformed code to running on AWS, with automated scripts that reduce manual setup and accelerate time to production.
