Platform pillars
A cleaner path from mainframe to modern delivery
Every engagement blends automated analysis with human review so your modernization team can prove equivalence, quantify conversion quality, and move forward faster.
Objective Quality Metrics
Metrics that objectively assess COBOL to Java conversions based on complexity, LOC ratio, and functional equivalence.
Live scorecard
Strust quality baseline
Verifiable Functional Equivalence
Parallel containers ensure identical outputs between your COBOL and Java systems.
Parallel validation
Prove runtime equivalence
0
Deterministic harnesses diff COBOL and Java outputs across datasets so you can certify results before cutover.
Independent Assessment
