Last week, ISG published a press release highlighting the myriad ways which firms in the US are enthusiastically embracing Generative AI (GenAI) in their efforts to modernize aging systems, particularly mainframes. This aligns closely with the recent 2025 ISG Provider Lens Mainframe Services and Solutions report where AveriSource was named a Rising Star, a designation ISG assigns to providers demonstrating a promising portfolio and significant future potential. As I read the release, I found myself nodding enthusiastically, while simultaneously recognizing the pivotal role that innovative tooling plays in navigating the complexities inherent in critical systems transformation.
AI-enabled solutions like the recently released AveriSource Platform 3.1 are on the cutting edge this trend. AveriSource is accelerating modernization projects by combining proven, repeatable automated analysis with the cognitive power of best-of-breed GenAI tools and techniques.
Hybrid Modernization: Bridging Legacy Systems and Modern Innovation
ISG’s article underscores how GenAI is revolutionizing legacy modernization by automating code translation, documentation, and testing. These capabilities are undoubtedly transformative, yet relying solely on GenAI doesn’t adequately address the multi-dimensional challenges of enterprise-scale modernization. Effective modernization demands deeper insights into complex legacy ecosystems, informed identification of interdependencies, and a comprehensive, hybrid approach. Modernization at scale requires tooling that can bridge legacy and modern architectures, enabling incremental, strategic modernization that reduces risk while maximizing control.
At AveriSource, we define hybrid modernization as a strategy-driven incremental journey that integrates multiple modernization approaches (all starting with “R”, of course). This enables enterprise stakeholders to optimize for their preferred balance of risk, cost and timeline while addressing evolving business processes and maintaining operational continuity. Rather than insisting on a wholesale replacement or a risky “all-or-nothing,” approach, hybrid modernization empowers organizations to modernize incrementally and intelligently while adapting, evolving, and integrating at a pace that matches their unique business requirements and risk tolerance .
Introducing AveriSource Platform 3.1: Legacy Reimagined
At AveriSource, we’ve been leading the charge in enterprise application modernization, consistently pushing boundaries with transformative solutions. Our latest release, AveriSource Platform 3.1, marks a significant leap forward in hybrid modernization, advancing the integration of powerful automated intelligence with cutting edge GenAI capabilities to deliver unparalleled precision, speed, and control.
Building upon our proven capabilities, AveriSource Platform 3.1 notably includes:
- Enhanced AI-driven application analysis and decision-making, accelerating discovery and improving accuracy in identifying legacy dependencies, redundancies, and complexities.
- A supercharged business requirements documentation engine, built to inform Agile rewrite, rearchitecture and reimagine projects by deriving user stories, epics, and initiatives from legacy assets.
- Fit-to-purpose visualization dashboards and workflows specifically designed to empower both business and IT stakeholders, enabling clear collaboration and total visibility across hybrid modernization initiatives.
- A comprehensive suite of intelligent modernization packages including AveriSource Scan, Inventory, Discover, Analyze, and Transform, powered by integrated GenAI functionality to automate and optimize complex hybrid processes that include refactoring, migration, and incremental modernization.
- Expanded GenAI-driven code generation and automated testing capabilities, significantly reducing manual effort and mitigating traditional modernization risks.
What differentiates AveriSource Platform 3.1 isn’t merely the integration of GenAI. It’s our robust automated intelligence engine. AveriSource intelligently assesses and prioritizes modernization initiatives, empowering enterprises to confidently pursue hybrid modernization strategies, minimize disruption, and maximize control for improved ROI.
Hybrid Modernization: Reimagining your Journey with Confidence and Clarity
The journey from mainframe to mainstream involves far more than just technology change. It’s about empowering organizations to evolve legacy systems strategically, preserving decades of embedded business logic while gradually transforming legacy applications into agile, scalable, and future-proof deployments. Hybrid modernization enables organizations to innovate incrementally, lowering costs and risks, and ensuring ongoing business continuity.
Incremental modernization presents a unique and daunting challenge. Modernized legacy functions often require data and functions still on the mainframe, In the past, the manual effort to identify and code modern-to-legacy “bridging” has pushed enterprises into risky “big bang” strategies. AveriSource and GenAI automate bridging to return control to business leaders.
With AveriSource, organizations confidently navigate their hybrid modernization, leveraging automated intelligence and GenAI to drive rapid, accurate, and strategic transformation. Whether migrating to cloud-native environments, incrementally refactoring monolithic applications into microservices, or optimizing existing portfolios, AveriSource means legacy reimagined.
Mainframes Still Run the World but Time is Running Out
As ISG rightly notes, mainframes continue to underpin crucial aspects of global commerce, finance, government, and healthcare systems. Despite their reliability, businesses increasingly realize these legacy systems serve as barriers to agility, scalability, and digital innovation. As such, most urgently seek pathways to modernize their legacy systems to unshackle the contents and enable faster response times, reduced operational costs, and improved customer experiences.
However, modernization efforts historically have been complex, costly, and time-consuming. To succeed, enterprises must carefully map decades of embedded business logic, untangle interdependencies, and migrate or rewrite this accumulated knowledge into modern languages, databases, and architectures. An endeavor where each task has the potential to consume vast resources while posing significant technical or financial risk.
