Summary
Organizations are increasingly adopting agentic AI, Generative AI (GenAI) and hybrid modernization strategies to accelerate legacy transformation while reducing risk. Recognized as a Rising Star in the 2025 ISG Provider Lens™ Mainframe Services and Solutions report, AveriSource combines proven deterministic automated application intelligence with agentic and GenAI capabilities to help enterprises modernize legacy systems with greater speed and confidence.
AveriSource Recognized as Rising Star in Mainframe Modernization
Organizations across industries are facing a common challenge: how to modernize critical legacy applications while minimizing risk, controlling costs, and maintaining business continuity. As modernization initiatives accelerate, agentic and Generative AI (GenAI) are emerging as powerful enablers to help enterprises analyze, understand, orchestrate, and transform complex legacy systems.
The momentum behind AI-powered modernization is reflected in the 2025 ISG Provider Lens™ Mainframe Services and Solutions report, where AveriSource was recognized as a Rising Star. The designation recognizes providers with a promising portfolio and strong future potential in the modernization market.
These developments underscore an important reality: successful modernization requires more than code conversion. Organizations must understand decades of accumulated business logic, application dependencies, and operational requirements while creating a path to more agile and adaptable technology environments. AI can accelerate this journey, but modernization outcomes depend on the quality, completeness, and traceability of the underlying application understanding.
The AveriSource Platform addresses this challenge by combining deterministic automated application intelligence with agentic AI and GenAI-powered capabilities. Together, these capabilities help organizations accelerate discovery efforts, coordinate modernization activities, generate transformation artifacts, and modernize legacy systems faster, with verified accuracy, traceability, and greater confidence.
Why Legacy Modernization Is Changing
For decades, organizations have relied on mainframe and midrange systems to support mission-critical business processes. These systems often contain valuable business rules, institutional knowledge, and operational workflows that remain essential to day-to-day operations.
However, changing customer expectations, increasing demands for agility, rising operational costs, and evolving technology requirements are forcing organizations to rethink how these applications support future business growth.
Traditional modernization approaches often require organizations to choose between maintaining legacy systems or pursuing large-scale replacement initiatives. These projects can be costly, time-consuming, and risky, particularly when critical business logic is poorly documented or deeply embedded within legacy codebases.
Today, organizations are increasingly seeking modernization strategies that provide greater flexibility while reducing implementation risk.
The Growing Role of Agentic and GenAI in Legacy Modernization
Agentic and Generative AI are transforming how organizations approach legacy modernization. Rather than relying exclusively on manual analysis and documentation, modernization teams can use AI-driven capabilities to help:
- Analyze and understand legacy codebases
- Generate application documentation
- Extract validated business rules
- Create business function specs, user stories, requirements, and modernization roadmaps
- Support testing, validation, and impact analysis activities
- Accelerate code transformatoin and delivery initiatives
By reducing manual effort and improving visibility into complex applications, agentic AI and GenAI help organizations make better-informed modernization decisions while accelerating project timelines.
At the same time, successful modernization requires more than AI-generated outputs or automated orchestration. Organizations still need comprehensive visibility into application architectures, dependencies, data flows, and business processes. Combining deterministic application intelligence with agentic AI and GenAI provides the trusted foundation needed to accelerate modernization while maintaining accuracy, traceability, and confidence.
What Is Hybrid Modernization?
Hybrid modernization is an approach that combines multiple modernization strategies to help organizations transform legacy systems incrementally rather than through a single large-scale migration. Instead of replacing an entire application portfolio at once, organizations can modernize specific components, business functions, or workloads while maintaining critical operations throughout the transition.
A hybrid modernization strategy may include:
- Modernizing selected applications while retaining others
- Supporting both legacy and cloud environments
- Incrementally replacing aging components
- Preserving valuable business logic and operational workflows
- Reducing risk through phased transformation
This approach allows organizations to balance modernization objectives with business continuity requirements while maintaining greater flexibility throughout the modernization journey.
How the AveriSource Platform Supports Hybrid Modernization
The AveriSource Platform combines deterministic automated application intelligence, deep modernization expertise, and agentic AI and GenAI-powered capabilities to help organizations accelerate modernization initiatives.
The platform is designed to provide visibility into complex application portfolios while helping organizations identify opportunities to reduce technical debt, improve efficiency, and support future modernization efforts.
Key Platform Capabilities
Together, these capabilities provide organizations with a clearer understanding of their legacy environments and a more informed path toward modernization.
Turning Application Knowledge Into Modernization Action
One of the greatest challenges in legacy modernization is understanding what an application actually does before attempting to change it.
Many legacy systems have evolved over decades, often with limited documentation and multiple generations of developers contributing to the codebase. Critical business processes may exist only within the application itself.
The AveriSource Platform helps organizations address this challenge by providing deeper visibility into:
- Application architectures
- Business rules
- Data relationships
- System dependencies
- Technical debt
- Modernization opportunities
By transforming application knowledge into actionable modernization insights, organizations can make more informed decisions and reduce uncertainty throughout modernization projects.
Why Organizations Are Embracing Hybrid Modernization
As modernization initiatives become increasingly complex, organizations are looking for approaches that deliver measurable business value while minimizing disruption. Hybrid modernization offers several advantages:
- Reduced modernization risk
- Faster project delivery
- Improved operational continuity
- Greater flexibility in modernization planning
- Better alignment between business and technology objectives
- More effective use of cloud and modern application architectures
When combined with agentic AI and GenAI-powered analysis and deterministic application intelligence, hybrid modernization enables organizations to move forward with greater confidence while preserving the business value embedded within their legacy systems.
The Future of Legacy Modernization
Legacy modernization is no longer simply about migrating applications from one platform to another. It is about understanding, preserving, and evolving the business capabilities that power an organization.
As AI continues to advance, organizations have new opportunities to accelerate modernization initiatives while improving visibility, reducing risk, and increasing efficiency.
The combination of hybrid modernization strategies, deterministic automated application intelligence, agentic AI and GenAI-powered capabilities is helping organizations transform legacy systems into modern, adaptable technology assets that support long-term business growth.
For organizations seeking a modernization approach that balances innovation with operational certainty, the AveriSource Platform provides a path forward—helping enterprises understand their legacy environments, preserve critical business knowledge, and accelerate modernization outcomes.
