Businesses running on IBM i (AS/400) systems are at a crossroads. Legacy infrastructure continues to power critical operations—but it’s also slowing down innovation, integration, and agility. The good news? IBM i modernization doesn’t have to be costly, disruptive, or overwhelming. With IBM i Modernization as a service (MaaS), companies can transform smarter, reduce risk, and unlock long-term value.
In this blog, we’ll explore why modernizing IBM i systems is essential, the challenges many organizations face, and how MaaS provides a modern, scalable solution using advanced AI tools to accelerate digital transformation.
What is IBM i Modernization as a Service (MaaS)?
IBM i Modernization as a service, or MaaS, is a subscription-based, scalable approach that helps businesses modernize their IBM i environments using automated analysis and strategic insights. Unlike traditional modernization, IBM i MaaS minimizes risk, avoids large upfront costs, and delivers measurable outcomes faster.
Key features of IBM i MaaS:
- AI-powered application analysis: Understand code structure, business rules, and data flows.
- Risk-managed modernization: Prioritize updates and reduce disruption.
- Scalable and flexible: Pay-as-you-grow, OpEx-friendly solution.
- Integration-ready: Supports APIs, cloud, and digital platform adoption.
Why IBM i modernization matters
Today’s enterprises need agile, connected, and intelligent systems, but many still rely on aging IBM i platforms that limit innovation. IBM i modernization unlocks the value trapped in these systems, enabling integration with modern technologies like AI, analytics, and cloud-native applications.
By choosing IBM i MaaS, organizations get the tools and expertise needed to:
- Reduce technical debt
- Extend the value of existing assets
- Align IT with modern business goals
Business challenges solved by IBM i Modernization as a Service
Organizations face several roadblocks when trying to modernize legacy IBM i systems. Here’s a look at common issues—and how IBM i MaaS provides a better path forward:
Legacy systems reduce business agility:
Rigid IBM i systems make it difficult to pivot quickly or adapt to new market demands. MaaS introduces flexibility by identifying critical components that can be modernized or integrated without complete re-platforming.
Limited internal skills and resources:
Most IT teams lack the bandwidth or deep IBM i expertise to drive modernization. MaaS brings in specialized knowledge and automation tools to supplement internal efforts and accelerate delivery.
Struggles integrating with modern systems:
Connecting legacy IBM i systems with cloud, web, or mobile platforms is often painful. MaaS simplifies this with deep code analysis and mapping, revealing safe and efficient integration paths.
Too much time spent maintaining old code:
Developers spend more time fixing legacy bugs than building new features. MaaS streamlines modernization and reduces the maintenance burden by optimizing codebases and improving visibility.
High upfront modernization costs:
Traditional modernization projects require large capital investments and approvals. IBM i MaaS provides a cost-effective, subscription-based model that spreads costs over time.
Difficulty adopting AI and data analytics:
IBM i environments are often incompatible with modern AI tools due to outdated data structures. MaaS helps modernize and expose data, enabling intelligent automation and machine learning initiatives.
Need for value-driven, incremental change:
Big-bang transformations are risky and rarely successful. MaaS enables phased modernization aligned with business value—without overhauling everything at once.
Benefits of IBM i Modernization as a Service
Implementing IBM i Modernization as a service brings immediate and long-term benefits:
- Deep visibility into code, data, and business rules
- Improved planning and prioritization of modernization initiatives
- Reduced project risk with AI-based analysis and automated insights
- Faster integration with APIs, cloud platforms, and modern apps
- Lower operational costs with an OpEx-based, flexible model
- Accelerated innovation by freeing up internal development teams
