IBM Power Modernization

Evolve your Power estate without disrupting the business.

Your IBM Power systems hold decades of business logic and mission-critical applications. Modernization isn’t about replacing IBM i, AS400 or AIX – it’s about evolving your Power platform and the critical applications that run on it, to unlock new capabilities while keeping operations stable.

Let’s Talk

Our IBM Power Modernization Approach

Understand What’s Working

We assess your IBM Power environment, application landscape, business goals, and integration requirements. Together, we build a phased roadmap that prioritizes high-value opportunities and minimizes disruption.

Modernize Infrastructure

Where appropriate, migrate legacy workloads to the latest generation of IBM Power 11 infrastructure delivered as-a-service by Ensono. Based on IBM benchmarks, newer generations deliver up to 2x better performance per watt, enhanced security, and AI acceleration – while maintaining compatibility with existing IBM i and AIX applications.

Modernize Applications

Modernize your code base (COBOL, RPG, or convert to Java) for agility, build APIs, update interfaces, and create secure cloud connectivity that bridges IBM Power and your modern technology stack – enabling real-time data access, automation, and AI-powered insights.

Optimize Costs

Reduce software and infrastructure costs through workload consolidation, right-sizing licensing and modern replication strategies aligned to actual usage.

Enable Hybrid Cloud

Modern IBM Power environments don’t operate in isolation. We help integrate IBM i and AIX workloads into secure hybrid cloud architectures – connecting Power systems with AWS, Microsoft Azure, and Google Cloud to enable real-time data exchange, AI initiatives, and modern digital services.

Start with a Strategic Modernization Assessment (SMA)

Ensono’s Strategic Modernization Assessment (SMA) uses AI-assisted code analysis to reverse‑engineer your IBM Power applications and understand how they operate. Our experts validate findings with your team and deliver a precise, fact-based modernization roadmap – faster and more accurately than traditional assessments.

We work with you to:

Define Goals & Drivers

Align stakeholders around measurable business outcomes.

Analyze Current State

Reverse-engineer applications using AI-assisted source code analysis to extract architecture, identify dependencies, assess security risks, and quantify technical debt – delivering a detailed technical insights for each application.

Rationalize & Strategize

Determine application disposition (Tolerate, Invest, Migrate, Eliminate) and recommended modernization pathways.

Build Strategic Roadmap

Deliver a sequenced, value-focused plan with quick wins and long-term initiatives.

Common modernization pathways include rehost, refactor, replatform, rearchitect, and replace – the 5 Rs of application modernization.
