Integrative Systems Applies AI to IBM i Modernization to Preserve Business Logic

Integrative Systems is applying AI to IBM i development and modernization to help organizations understand complex applications, preserve critical business knowledge and prepare established technology environments for future innovation, the company said in a PRLog announcement on November 5, 2026. The Lombard, Illinois-based IT services and software development company combines AI capabilities with IBM i expertise.

How Integrative Systems Applies AI to IBM i

IBM i environments often contain years of accumulated business rules, RPG programs, interconnected applications and operational knowledge. Limited documentation and a shrinking pool of experienced IBM i professionals can make application maintenance and modernization increasingly challenging, according to the company.

Integrative Systems integrates AI throughout the IBM i modernization lifecycle, beginning with application discovery and readiness assessment. AI-powered tools analyze RPG and CL code, interpret embedded business rules, identify application dependencies and accelerate technical documentation. These insights help development teams determine which components should be preserved, enhanced, integrated or replaced.

AI also supports development research, code reviews, knowledge extraction, developer onboarding and test-case generation. During modernization, AI-assisted impact analysis and regression testing preparation can help developers investigate application changes and identify potential risks. The development approach incorporates Git, VS Code and free-format RPG while maintaining validation of critical business functionality.

The company's AI Readiness Assessment examines application documentation, data accessibility, integration preparedness, development practices, talent-related knowledge gaps and alignment between AI initiatives and business objectives. The assessment helps organizations identify readiness gaps and establish a roadmap for practical AI adoption.

"AI is creating new opportunities for IBM i modernization while helping organizations preserve the business logic behind their operations," said Stephanie Rabbani, IBM i Engagement Manager at Integrative Systems. "By combining AI-assisted development with deep IBM i expertise, we help businesses make informed modernization decisions and prepare their environments for future innovation."

Integrative Systems' IBM i Ecosystem Position

According to akta.pro company records, Integrative Systems holds IBM Silver Business Partner status, which gives it access to co-sell opportunities, IBM's customer ecosystem and technical enablement resources for delivering IBM i/AS400 consulting, modernization and managed services. The same records show the company has worked with 85+ clients globally, with over 90% client retention, and established a Centre of Excellence in Pune, India housing IBM i developers, JDA developers, cybersecurity analysts and project management staff to complement its Chicago headquarters.
