Integrative Systems Applies AI to IBM i Modernization While Preserving Critical Business Logic

LOMBARD, Ill. - EntSun -- 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 combines AI capabilities with extensive IBM i expertise to help businesses identify modernization opportunities while retaining the core business logic that supports their operations.

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. AI offers new opportunities to address these concerns through application analysis, knowledge extraction, documentation, and development support.

The company's approach integrates AI throughout the IBM i modernization lifecycle, beginning with application discovery and readiness assessment. AI-powered tools help analyze RPG and CL code, interpret embedded business rules, identify application dependencies, and accelerate technical documentation. These insights help development teams understand existing environments and 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 modern practices and tools, including Git, VS Code, and free-format RPG, while maintaining appropriate validation of critical business functionality.

Its 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."
