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

Unbiased quality benchmarks for mainframe modernization projects.

Third-party rigor

Evidence beyond internal teams

External reviewers sign off each metric before it is published.

Narrative commentary captures risk and remediation guidance.

Benchmarks stay consistent release-to-release for leadership reporting.

Built for Enterprises

Tailored for organizations undertaking critical mainframe modernization.

Enterprise delivery

Scaled reviews for complex estates

Security cleared reviewers

Assessments shipped through SOC 2-aligned workflows.

Lifecycle integration

API hooks feed findings into Jira, ServiceNow, and custom dashboards.

Cross-Version COBOL Compatibility

Our service ensures bit-for-bit equivalence across all Enterprise COBOL versions, legacy systems, and mainframe dialects.

Version coverage

One harness for every dialect

Enterprise COBOL 6.3
Enterprise COBOL 5.2
Enterprise COBOL 4.2
IBM COBOL z/OS
Micro Focus COBOL
Legacy VS COBOL II

Regression packs normalize dialect differences, preserving behavior for every runtime you depend on.
