Posted on: May 15, 2025

AWS Transform for mainframe, previewed as “HAQM Q Developer transformation capabilities for mainframe” at re:Invent 2024, is now generally available. AWS Transform is the first agentic AI service for modernizing mainframe applications at scale—accelerating modernization of IBM z/OS applications from years to months.

Powered by a specialized AI agent leveraging 19 years of AWS experience, AWS Transform streamlines the entire transformation process—from initial analysis and planning to code documentation and refactoring—helping organizations to modernize faster, reduce risk and cost, and achieve better outcomes in the cloud.

This release introduces significant new capabilities. Enhanced analysis features help teams identify cyclomatic complexity, homonyms, and duplicate IDs across codebases, with new export and import functions for file classification and in-UI file viewing and comparison. Documentation generation now supports larger codebases with improved performance and recovery capabilities, including an AI-powered chat experience for querying generated documentation. 

Teams can use improved decomposition features to manage dependencies and domain creation, while new deployment templates streamline environment setup for modernized applications. The service also introduces flexible job management, allowing teams to modify objectives and focus on specific transformation steps during reruns. 

AWS Transform for mainframe is available in the following AWS Regions: US East (N. Virginia) and Europe (Frankfurt).
