Mainframe Migration
Automated conversion of legacy mainframe assets to cloud-native platforms.
Mainframe Migration
QuickCloud Mainframe Migration converts COBOL, JCL, RPG, NATURAL, DMSII, HP TAL, and 150+ other legacy asset types to Java, Python, C#, Node.js, and microservices — with AI-powered business rules extraction and full rollback support.
Supported source platforms
| Platform | Asset types |
|---|---|
| IBM z/OS | COBOL, JCL, CICS, IMS, DB2 stored procedures, REXX, PL/I |
| IBM AS/400 (iSeries) | RPG II/III/IV, CL, DDS, physical and logical files |
| Unisys | DMSII, COBOL74/85, ECL, WFL |
| HP NonStop (Tandem) | TAL, COBOL85, TACL, Enscribe |
| NATURAL / ADABAS | NATURAL, DDMs, system files |
Supported target platforms
- Languages: Java 17+, Python 3.11+, C# / .NET 8, Node.js 20+
- Architecture: Monolith, microservices, serverless (AWS Lambda, Azure Functions)
- Cloud: AWS, Microsoft Azure, Google Cloud Platform
How it works
- Scan — the scanner inventories all assets in your mainframe environment and produces a dependency graph
- Analyze — Claude AI extracts business rules, identifies coupling, and scores each asset for conversion complexity
- Convert — automated code conversion runs in parallel; complex rules are flagged for human review
- Validate — parallel-run mode runs the converted application alongside the mainframe for output comparison
- Cut over — phase gate enforcement ensures each validation milestone is met before the next phase begins
Key features
- 150+ asset types — broadest coverage in the market
- AI business rules extraction — powered by Claude, routed through your tenant-isolated AI Gateway
- Self-healing via Gateway — runtime anomalies are detected and routed back through the AI Gateway for auto-remediation
- Parallel-run validation — side-by-side output comparison before decommissioning the mainframe
- Full rollback — every phase is reversible; no destructive changes to the source environment
