# ADABAS/NATURAL to Cloud-Native Microservices

See how IONATE replaced a full Software AG ADABAS/Natural application stack with open-source Java microservices — eliminating proprietary licensing while preserving every business rule.

## What the Demo Shows

A complete ADABAS/Natural application — taken from proprietary Software AG infrastructure to open-source Java microservices running on Kubernetes, with zero data loss.

### The Legacy System

An enterprise application built on Software AG's ADABAS database with Natural 4GL programs. Decades of business logic in Natural subroutines, DDMs, and ADABAS file descriptors — all proprietary, all at end-of-life risk.

### The Transformation

SOTERIA maps every ADABAS file, descriptor, and Natural program. APPDATE converts Natural code to Java microservices and maps ADABAS data structures to a modern database — automatically, with full validation.

### The Result

Java microservices on Kubernetes. ADABAS replaced by PostgreSQL or MongoDB. Natural programs become Spring Boot services. No Software AG license required — ever again.

## Watch the Before/After Video

The full demo shows the SOTERIA discovery output for an ADABAS estate, APPDATE's Natural-to-Java conversion in action, and the final Kubernetes deployment — with side-by-side validation confirming every business rule preserved.

D.A.T.E.D. Applied to ADABAS/Natural

## Five Phases. Zero Big-Bang Risk.

The same structured process that handles COBOL handles Natural — every step AI-driven, every business rule extractable, the production system untouched until cut-over.

### Discover

SOTERIA inventories every ADABAS file, descriptor, DDM, Natural program, and subprogram. Complete cross-reference mapping — data access patterns, call hierarchies, and transaction flows — before any migration begins.

### Analyze

Business logic extracted from Natural subroutines, IF/DECIDE structures, and ADABAS Find/Read loops. Every program scored by complexity and migration risk. Full audit trail, no sampling.

### Train

Domain models learn your Natural dialect, ADABAS access patterns, and business semantics. Transformations are specific to your estate — not generic Natural patterns.

### Execute

APPDATE converts Natural → Java Spring Boot, ADABAS files → relational/NoSQL, DDMs → JPA entities, and batch Natural jobs → Spring Batch — with full business rule preservation.

### Deploy

KÍRKĒ orchestrates phased rollout on Kubernetes. ADABAS stays live until each Java service is validated and cut over. Cloud-agnostic: on-prem, AWS, Azure, or GCP.

### MIRA Codex Studio

MIRA Codex Studio is trained on Natural and ADABAS patterns accumulated across 500M+ lines of legacy code. It extracts business rules buried in ADABAS call structures, maps complex DDM hierarchies to relational schemas, and generates production Java — autonomously, in your air-gapped infrastructure.

**Natural Rule Extraction**  
Extracts business logic from Natural subroutines, DECIDE blocks, and ADABAS Find loops — rules often invisible in the DDM layer.

**ADABAS Schema Migration**  
Maps ADABAS files, descriptors, and coupled groups to normalized relational schemas or document models — no manual DBA work required.

**Air-Gapped & Secure**  
Runs entirely in your infrastructure. No Natural source or ADABAS data sent externally. Bring your own LLM. SOC 2 compliant.
