IBM i modernization means improving the parts of your system that limit growth, usability, integration, or maintainability while keeping IBM i as the stable core. That can include application code, green-screen interfaces, database structures, and connected workflows. Fresche has focused exclusively on IBM i modernization since 1976.
Every organization’s modernization needs are different. Some need to update legacy code, some need to improve the user experience, and others need better access to data for integration, reporting, or new applications. Fresche helps you focus on the areas that need your attention now, whether that means starting with one service or combine several.
Move your RPG, COBOL, or Synon applications to a modern language, with your existing business logic intact. AI-assisted conversion runs about 50% faster than a manual rewrite.
Build portals, dashboards, and mobile tools that extend what your IBM i applications already do. Give users and customers self-service access without rebuilding your core.
Move Db2 from DDS to DDL and ready your data for analytics, integrations, and API-driven applications. Same trusted data, a more usable foundation.
Replace green screens with a browser-based interface that works on desktop and mobile. No replatforming and no backend changes required.
See how Fresche built a custom self-service utility billing portal on IBM i, giving residents 24/7 account access without replacing the system behind it.
Fresche’s Modernization as a Service (MaaS) gives you a phased, pay-as-you-go way to modernize IBM i based on your priorities, your timelines, and your budget. Start with one service or combine several, then expand over time as needs change. Instead of forcing modernization into one large project, MaaS lets you move forward in stages with clear progress along the way.
AI-assisted modernization transforms legacy applications about 50% faster than a manual rewrite, and it produces clean, maintainable code.
A subscription-based model spreads cost over time. No large upfront commitment to get started.
Each phase delivers a working result you can measure. You see ROI early instead of waiting for one large finish line.
Modern languages open your applications to a wider talent pool, so you rely less on hard-to-find IBM i specialists.
Move to modular, portable technologies that connect cleanly with cloud, data, and API-driven tools.
You keep full ownership of your modernized applications, with no dependency on Fresche to run them.
Behind our IBM i modernization services is a set of tools built specifically for your environment. They read, map, and transform your applications with context that generic tools miss.
Map the dependencies and business rules across your application portfolio before any change is made.
AI accelerates RPG and code transformation while reducing rework, with over 10 million lines of RPG converted.
Modernizes green-screen interfaces to browser-based UIs without rewriting core applications.
IBM i modernization is the process of improving the code, interface, database, or connected workflows running on IBM i so the system is easier to use, maintain, integrate, and extend.
No. Modernization often focuses on improving the code, user experience, or data layer while keeping IBM i in place as the core business platform.
Yes. A phased approach lets organizations start with the area that matters most, reduce disruption, and expand over time as priorities and budget allow.
MaaS is Fresche’s phased, pay-as-you-go approach to IBM i modernization. Instead of one large project, you choose the services you need now, RPG transformation, UI modernization, database upgrades, or custom development, and add more as priorities and budget allow.
Most legacy IBM i system upgrades involve some combination of code transformation, UI modernization, and database upgrades, sequenced based on what’s causing the most disruption to the business right now.
Most teams start with the area causing the most pain. That may be application maintainability, green-screen usability, data access, integration limitations, or staffing risk.
They refer to the same platform family. AS/400 and iSeries are earlier names for what IBM now calls IBM i.
Yes. UI modernization can provide a browser-based experience without requiring replatforming or changing the underlying business logic.
Code modernization focuses on maintainability and application evolution. UI modernization focuses on usability and access. Database modernization focuses on making data easier to integrate, report on, and extend.
That depends on the scope. Some phased efforts can deliver useful improvements in weeks, while broader modernization programs take longer. The key is defining a practical starting point and sequencing work based on business value.
Often, yes. Modernizing code, interfaces, or database structures can make it easier to connect IBM i to APIs, web applications, cloud services, reporting tools, and analytics platforms.
Modernization gets easier once you know your starting point, your priorities, and your first quick win. Talk with a strategic advisor at no cost to define your phased roadmap, reduce risk, and target the work that delivers the most value first. You move from assessment to action with a clear next step, not a rip-and-replace project.
