Imogen
Mechanical Orchard
Mechanical Orchard’s Imogen platform rewrites mainframe applications with confidence by using real data flows, not just code translation, to safely rebuild aging systems into modern code. Legacy modernization is often slowed by stopgap patches, cloud emulation, technical debt, integration risk, and high-stakes cutover moments, but Imogen changes the risk equation with a behavior-first, test-driven approach. Instead of focusing only on code, Imogen captures how individual workloads actually behave through real data flows and creates a precisely equivalent behavioral replica of a complex system through a clear, iterative, and transparent process. It builds a precise behavioral specification from the running system, then applies a closed loop of rapid code generation and verification against those specifications, creating software that is audit-quality, idiomatic, and ready for what comes next. -

Assembler Code Refactoring
Rocket Software
Rocket Assembler Code Refactoring is a specialized modernization solution that automatically restructures legacy Assembler code into structured pseudocode or modern languages such as COBOL, C, or Java without altering external behavior, enabling faster, lower-risk modernization and improved maintainability. Assembler code is notoriously dense, poorly documented, and supported by a shrinking pool of specialists, making maintenance slow, costly, and error-prone; this product addresses those challenges by delivering semantics-preserving, auditable transformations that reduce outages and secure modernization without sacrificing stability. Its fully automated core engine uses mathematically guaranteed logic equivalence to eliminate conversion risk, dramatically accelerating projects while ensuring that refactored outputs are semantically identical to the original code. -

CodeTurn
Astadia
CodeTurn is Astadia’s automated mainframe code conversion product, built to automatically transform legacy source code into modern source code that is maintainable and 100% functionally equivalent to the original. It takes an application’s source code and converts it to functionally identical sources, ready to run in an alternative environment on the same platform or on a different platform altogether. Because the conversion and testing are fully automated, the outcome of the modernization project becomes highly predictable in terms of risks, costs, and duration. The migrated application is free of dependencies on proprietary Astadia software and relies on native industry-standard technologies instead. CodeTurn integrates all aspects of conversion to produce high-quality, functionally equivalent code and is typically used with Astadia tools such as DataTurn for legacy data migration, TestMatch for automated testing, and DataMatch for automated batch testing. -
