Your IBM i isn’t the problem.
What surrounds it may be.

Years of trusted business logic still run reliably on IBM i. But dated interfaces, scarce RPG/COBOL skills, integration friction and tightly coupled applications can make change slower and riskier than it needs to be.

Your business needs to move faster, and put AI to work. Is your IBM i estate ready?

Your IBM i holds decades of valuable business logic and data. But green screens, complex integrations and reliance on a few specialists can make change difficult. Bringing AI into everyday workflows takes more than a fresh interface. Copilots and agents need reliable access, business context and clear controls to work effectively.

Manual workflows slow the business

Disconnected screens and repetitive data entry make everyday tasks harder to complete and automate.

Critical knowledge is concentrated

Poorly documented RPG/COBOL logic and dependence on key specialists increase maintenance and change risk.

Integration takes too much effort

Point-to-point connections make it harder to share current data and business functions with modern applications.

AI needs a stronger foundation

Limited APIs, fragmented data access and undocumented rules make it difficult to ground AI in your operations and let it act safely.

ARCHITECTURE

One partner. Three paths to an AI-ready IBM i estate.

A spectrum, not a switch. Start where it makes sense and move deeper when the business is ready.

01 / MODERN ACCESS

Get to the web, fast.

Web-enable existing green-screen applications with minimal change. No rewrite. No data migration. Your proven business logic and DB2 data stay on IBM i.

Best for: quick wins, browser/mobile access and coexistence while deeper modernization is planned.

02 / MODERN EXPERIENCE

Transform how people work

Rebuild screen and interactive programs as a true modern web application. Redesign workflows and UX while proven backend programs and the database remain on IBM i.

Best for: modern UX, workflow transformation and integration without re-architecting the backend.

03 / MODERN CORE

Transform the application.

Reverse-engineer screens, interactive programs and backend/batch RPG and COBOL, then rebuild them as a modern web application on a microservices architecture. Retain or migrate data as the target architecture requires.

Best for: full transformation, architectural renewal, scalability and cloud-ready modernization.

Understand first. Modernize second.

RAPIDIT combines deep IBM i engineering with AI-assisted discovery, reverse engineering, development and transaction-level validation.
The goal is not to convert code faster for its own sake — it is to modernize safely with the business logic understood and proven.

01

Discover & map

Inventory programs, jobs, data structures, call streams and dependencies.

02

Recover the logic

Extract and document the business rules embedded in RPG / COBOL.

03

Design the target

Define service boundaries, modern UX, APIs and coexistence architecture.

04

Build with acceleration

Use AI-assisted development for modern services, APIs and web apps.

05

Validate in parallel

Run legacy and modern side by side and compare transaction outputs.

06

Roll out in phases

Modernize by module, workflow or persona — without a big-bang migration.

Modernization at scale. Measurable business impact.

IBM i modernization succeeds when business logic is understood,
outcomes are measured, and the new system is proven against the original

IBM i DNA since 1996

DAMCO began as a pure AS/400 shop. IBM i modernization is a core capability, not an adjacent practice.

Deep reverse engineering

Recover the real business logic from RPG / COBOL before transformation begins.

One partner, end to end

From quick browser enablement to complete re-architecture, with clear ownership throughout.

Coexistence by design

Modernized and legacy options can live behind one consistent experience while transformation progresses.

Low-risk, incremental delivery

Create value early and manage risk through phased modernization rather than a forced cutover.

Modern target architecture

Responsive web front ends, APIs and cloud-ready microservices built for long-term change.
