Beta · Enterprise · Requires DB Schema Migrator

COBOL in,
Spring Boot out

Legacy Auto-Upgrade generates working Java — Spring Boot services, JPA entities and unit tests — directly from your analysed COBOL programs and migrated schema. Not a translation exercise: a working starting point your developers can actually build on.

What it generates

Working code, not a translation exercise

Every generated bundle is built from your actual COBOL business logic and your actual migrated schema — not a generic template.

⚙️
Spring Boot services
Each COBOL program becomes a Spring Boot service with the original business logic preserved — not line-by-line syntax conversion.
🗃️
JPA entities
Generated directly from your migrated PostgreSQL schema, so the Java data layer and the database are consistent from day one.
✅
Unit tests included
Every generated service ships with a starting test suite, so your team isn't reviewing untested code from scratch.
🔍
Automated build verification
Every generated bundle is scanned before delivery — reflection usage and other AI-codegen red flags are caught automatically.
How it works

From analysed COBOL
to a Java bundle

01

Complete Discovery + Schema Migration first

Legacy Auto-Upgrade generates against an existing PostgreSQL schema plan — Discovery and DB Schema Migrator are hard prerequisites, not optional.

02

Select programs, generate

Pick which COBOL programs to upgrade. AI-powered code generation runs in the background — no need to babysit it.

03

Download your bundle

One ZIP per run: Spring Boot services, JPA entities, JUnit tests — ready to open in your IDE and keep building.

Pricing

One module, Enterprise-grade
