Modernization Journey

Phase-by-Phase RPG to Java Codebase Transformation

Modernizing mainframe RPG/CL workloads requires structured, automated pipeline steps. Below is the blueprint of how as400toaws.com delivers full containerized parity.

1

Catalog & Map

Audit source files, logic loops, physical files, and dependencies using our mapping engine.

2

Logic Refactoring

Convert RPGLE statements into Object-Oriented Java 21 Spring Boot microservices automatically.

3

Database Shift

Map IBM i DB2 data structures to AWS Aurora PostgreSQL serverless architectures cleanly.

4

API Integration

Deploy refactored code onto Tomcat 10 container clusters using platform hooks.

5

Parallel Run UAT

Verify UI screens and transaction consistency against the live database before final cutover.
