Overview

AI-accelerated mainframe migration to cloud-native architecture

Kumaran's Mainframe Modernization Platform accelerates the migration of legacy COBOL/CICS applications into modern, cloud-native architectures. Using a combination of automated source analysis, Neo4j knowledge graphs and Generative AI code generation, the platform migrates the full application stack - UI screens, business logic APIs and nightly batch jobs - while preserving every business rule with full fidelity.

The platform has been proven on production applications, delivering a complete Angular front-end, Spring Boot middleware and Spring Batch batch processing tier, with human-in-the-loop validation at every critical phase.

Why Modernize

Why Enterprises Are Moving Away From Legacy Mainframes

Organizations running mainframe workloads face mounting pressures that make modernization both urgent and complex:

Aging COBOL Codebase

Decades-old COBOL programs are difficult to maintain, extend or document without specialized expertise.

High Operational Costs

Mainframe licensing, MIPS charges and infrastructure costs continue to escalate year over year.

CICS Screen Complexity

BMS-based screens are tightly coupled to mainframe infrastructure with no web-equivalent counterpart.

Batch Job Dependencies

Complex JCL-COBOL batch jobs for EOD processing are fragile and hard to migrate incrementally.

Scarce Mainframe Talent

The shrinking pool of COBOL/JCL developers creates organizational and operational risks.

Risk Of Data Loss

Migrating VSAM and relational data without business-logic fidelity risks critical data integrity failures.

Our Solution

What Makes Our Migration Platform Different

Kumaran's platform addresses these challenges through a structured, AI-accelerated migration methodology:

Source Parsing & Metadata Extraction

All COBOL programs, copybooks, BMS screens and JCL streams are parsed into a rich structured metadata format, forming the single source of truth for migration.

Knowledge Graph (Neo4j)

Metadata is loaded into a Neo4j graph database capturing parent-child relationships across business groups (Account, Card, Transaction, BillPayment) and their operations.

GenAI-Driven Code Generation

Generative AI prompts translate knowledge-graph nodes into working Angular components, Spring Boot service layers and Spring Batch job implementations.

Human-In-The-Loop Validation

SME review gates before and after code generation ensure business correctness, with IDE-based compilation and runtime error correction built in.

End-To-End Deployment

Angular UI, Spring Boot APIs and Spring Batch jobs are deployed together as a unified cloud-native application with Azure SQL as the backend datastore.

How It Works

Our Proven Seven-Step Migration Methodology

The migration follows a structured 7-step process from analysis to deployment:

  1. Step01

    Source Analysis

    Parse all COBOL programs, copybooks, JCL job streams and BMS screens to extract structured metadata.

  2. Step02

    Knowledge Graph

    Load parsed metadata into Neo4j to capture relationships, workflows and business groups across all components.

  3. Step03

    Human-In-Loop Validation

    Review groups, operations and workflows with business SMEs before committing to migration targets.

  4. Step04

    UI Generation (Angular)

    Select design templates; GenAI converts BMS screens into modular Angular components with Material controls.

  5. Step05

    Backend Generation (Spring Boot)

    GenAI creates Entity, Repository, Service, Controller and DTO layers from COBOL business logic.

  6. Step06

    Batch Generation (Spring Batch)

    JCL-COBOL batch jobs (PostTransaction, InterestCalculation, StatementGeneration) converted with Azure SQL.

  7. Step07

    Validation & Deployment

    All applications compiled, IDE-validated and deployed together for complete end-to-end online + batch flow.

FAQ

Frequently Asked Questions

The platform supports COBOL programs, copybooks, JCL job streams, BMS screens, VSAM datasets and DB2 datasets.
Angular (UI), Spring Boot (middleware / APIs), Spring Batch (batch jobs) and Azure SQL (data store).
COBOL programs are parsed at the paragraph level into a Neo4j knowledge graph. GenAI then reconstructs equivalent Java / TypeScript logic with SME review gates.
Yes. Human-in-the-loop validation occurs after metadata extraction, before code generation and during IDE compilation, ensuring accuracy at every step.
JCL-COBOL batch flows are migrated to Spring Batch with Azure SQL as the datastore.
Each group generates a modular Angular workspace with component.html, component.ts, model.ts and service.ts files mapped from BMS screens and CICS logic.
