OL AtomIQ
Decompose a z/OS or IBM i monolith one piece at a time: analyze COBOL and RPG, find operations and domains, trace data lineage, capture regression tests, and route cross-app calls as you decouple.
OL AtomIQ helps teams modernize a mainframe or IBM i monolith one piece at a time. It imports COBOL, RPG, copybooks, JCL, procedures, and screen maps from z/OS and IBM i, builds a graph of programs, data, and dependencies, and finds the business operations and domains inside it. Teams can capture regression tests for legacy behavior, decouple domains into separate apps, and route the remaining cross-app calls through a gateway, so each step is explicit, approvable, testable, and reversible.
