Enterprise platforms

Your last RPG developer is retiring. Ours are not.

Business-critical operations still run on AS400 while the talent pool shrinks. Aztia runs one of the largest active RPG practices in the Americas, keeping the platform sharp and future-ready for enterprise clients, most of them in financial services.

02
Modernization
Incremental modernization that never stops the business: API layers over legacy programs, integration with modern stacks, and staged migration paths.
03
Dedicated PODs
A POD of 5 developers plus a lead, fully managed by Aztia, dedicated to your platform. Knowledge stays in the team, not in one retiring employee’s head.
FAQ

Questions we always get

Do you do new development or only maintenance?

Both. Our teams write new RPG IV and free-form code, evolve DB2 data models, build integration layers, and also carry production support and incident response.

How big is your AS400 practice?

Over 50 dedicated RPG/iSeries developers, delivering around 8,000 hours per month for one of LATAM’s largest financial institutions, alongside other enterprise clients.

Our RPG veterans are close to retirement. How do you handle knowledge transfer?

That is the most common reason clients call us. We run structured knowledge-transfer alongside your current team while they are still available, document as code and specs in the repo, and staff a POD that absorbs the platform before the deadline hits.

What does the engagement look like?

The standard unit is a POD of 5 developers plus a lead, fully managed, on US hours, under a US-to-US contract signed with our St. Petersburg, FL entity. Staff augmentation for individual RPG profiles is also available.

AI-assisted modernization

What AI changes about legacy migration.

A pilot built with SETI, our parent company, by the group's AI practice. See RPG to Java migration in depth or the wider AI practice.

GROUP AI PILOT · LEGACY MODERNIZATION
Multi-agent code migration: RPG to Java in minutes
The problem: modernizing legacy code is slow, risky and manual. In this client's case, a team of more than five people needed over two sprints to migrate a single RPG component, below 80% effectiveness, with API documentation written by hand.
The solution: a multi-agent AI migration tool that transforms legacy code into modern systems: one engineer runs a whole project, with several components and their dependencies, and gets automated API documentation and Azure DevOps integration.
The impact: a full project migrates in under 10 minutes at 90 to 95% effectiveness, with manual effort, risk and cost cut accordingly.
How it was built: LangChain and LangGraph orchestrate specialized agents that analyze the legacy code, generate the modern equivalent and document the APIs, with embeddings and analysis results stored in MongoDB. Python backend, Streamlit and Angular front ends, all deployed on AWS with Terraform and Docker and wired into Azure DevOps for repositories and work items.
