Modernize legacy transaction programs without the risk of a full rewrite.
Convert CICS/BMS, IMS/MFS, RPG/DSPF, and RPC programs into runnable modern Groovy while preserving behavior first, validating in-browser, and hardening toward cloud-ready services over time.
How it works
1. Preserve and translate
Use OL Next migration kits to convert legacy screen and RPC programs into runnable Groovy, keeping behavior stable before deeper modernization.
2. Validate in-browser
Exercise interactive programs with players, RPC input and output forms, and Groovy screen flows so teams can confirm functional equivalence early.
3. Refactor in phases
Progress from faithful conversion to refactor or aggressive OO styles, with options for cursor-to-pagination and file-to-DB access modernization.
Modernization outcomes
Lower-risk incremental change
Refactor in controlled phases instead of committing to a disruptive full rewrite up front.
Runnable modern Groovy
Move screen and RPC programs into a modern language target while retaining the execution paths teams need to test.
Service-shaped preparation
Use OL Code screen-to-RPC conversion when needed to prepare COBOL for service-oriented refactoring before or alongside OL Next.
Modernized data access
Harden applications with DB access management patterns, including cursor-to-pagination and file-to-DB modernization.
