Rewrite / conversion
Automated code transformation preserving business logic
TSRI's JANUS Studio automatically analyzes and converts COBOL, JCL, CICS, IMS, Assembly, and more than 30 other languages into Java, C#, or C++ on multi-tier or microservices architectures, aiming to preserve the original business logic rather than reinterpret it. TSRI holds the AWS Mainframe Modernization Competency.
Large COBOL or Assembly codebases where preserving exact business logic during conversion matters more than a full architectural redesign.
