A contractor supporting a critical mainframe modernization project for a state government agency, faced a significant challenge. Tasked with migrating a legacy COBOL system, the contractor’s initial pilot migration attempt using AWS Blu Age could not fully meet customer requirements. The tool could only output Java and not meet the new requirement for Python or C#. Furthermore, the migration lacked traceability, making it impossible to validate. This contractor engaged Karsun Solutions, which leveraged its AI-powered ReDuX modernization platform. Using Agentic AI capabilities powered by Amazon Bedrock, ReDuX automatically analyzed the legacy system and generated the required C# programs, Summer Batch Core workflows, and MS SQL Server tables, delivering the 100% traceability needed to successfully complete the pilot.

About the Customer

The customer was one of three vendors awarded a contract for a cloud services project for a state government agency. This project’s goal is to modernize a core business system by converting legacy mainframe code to Python or C# while moving to a cloud-based platform.

Customer Challenge

A state government agency initiated a high-priority project to convert its legacy system to a modern, cloud-based platform. The state’s primary goals were to enhance security, improve flexibility, ensure data redundancy, and lower long-term maintenance costs.

The project was structured in two phases: a competitive part one pilot awarded to three bidders, followed by a part two award for the full system conversion given to a single winner from the pilot. The customer team was tasked with migrating a subsystem for the pilot, as it was the least entangled with other subsystems.

The customer’s initial modernization attempt hit two critical roadblocks. First, the agency’s requirements evolved. After initially preferring Java, the state later specified a preference for Python or C#. This immediately put the team’s approach in jeopardy, as AWS Blu Age can only create code in Java. Second, they were unable to show file-level COBOL program traceability to modern programs. This made validation and future maintenance impossible in the mind of the customer. Failure to solve these challenges would result in a failed pilot and disqualification from the lucrative part two of the contract.

The Partner Solution

The pilot contract was explicitly for cloud services. The state agency sought the enhanced security, flexibility, and redundancy that a cloud-native solution provides. The successful solution embraced this by using a suite of AWS-native services. Additionally, Karsun used its AI-powered modernization platform, ReDuX, to solve complex traceability problems in legacy systems and could output modern C# code, directly meeting the new requirements.

The ReDuX platform rapidly analyzed the system and generated a fully modernized, traceable equivalent.

1. Agentic Analysis: First, Karsun used its ReDuX Blueprint tool. This tool, which is powered by Amazon Bedrock, applied GenAI models to analyze the system, including COBOL programs, JCL, and DB2 database tables. This process created a comprehensive and fully documented map of the legacy system’s architecture and business logic.
2. Automated Transformation: With this detailed blueprint, Karsun’s ReDuX Code Companion used agents to automatically transform the legacy application. The modernized solution consisted of:
   • Agentic Analysis: First, Karsun used its ReDuX Blueprint tool. This tool, which is powered by Amazon Bedrock, applied GenAI models to analyze the system, including all COBOL programs, JCL, and DB2 database tables. This process created a comprehensive and fully documented map of the legacy system’s architecture and business logic.
   • Automated Transformation: With this detailed blueprint, ReDuX Code Companion used agents to automatically transform the legacy application. The new, modernized solution consisted of:
     • Modern C# Application: C# programs were generated for every COBOL program. Verifiable, one-to-one mapping solved the traceability problem. This new application is hosted on .NET Core containers over the AWS EKS service or on EC2 instances.
     • Cloud-Native Batch Processing: Summer Batch Core workflows were generated for every JCL, converting all mainframe batch processes into cloud-native, serverless workflows.
     • File Storage: Application files are now stored in AWS S3.
     • Angular Front-End: A new user interface in Angular precisely mimicks the flow of the original mainframe green screens, such as the menu and work order creation screens.
     • MS SQL Server Tables: Every legacy DB2 database table was migrated to a new table in MS SQL Server.

Results and Benefits

Karsun’s AI-powered ReDuX platform successfully delivered a modernized pilot application that met all of the state’s requirements, rectifying the failures of the initial attempt. The primary benefit was the achievement of 100% traceability for the entire application stack.

The key success metric was the one-to-one mapping of legacy assets to modern, cloud-native code, all made possible by the GenAI analysis from AWS Bedrock:

• Every COBOL program was converted to a corresponding C# program, now running in .NET Core containers on AWS EKS or EC2.
• Every JCL was converted to a Summer Batch Core workflow.
• Every DB2 table was migrated to an MS SQL Server table.

This provided the customer with a complete, verifiable, and maintainable modern application, allowing them to successfully complete the pilot.

One of Karsun Solutions’ government agency customers manages critical certification systems processing millions of applications globally. This agency partnered with Karsun to modernize its legacy Software AG Natural and ADABAS mainframe system used for its certification workflows. It had demonstrated expertise in mainframe modernization and clear competency in these environments. It had also previously delivered secure, compliant cloud solutions meeting federal requirements for this customer.

It migrated the system to Amazon Web Services (AWS) using modern code deployed on Karsun’s container platform. The modernized system eliminated mainframe dependencies, reduced operational costs, enabled modern integrations, and positioned the agency for continuous innovation while maintaining seamless processing for millions of certifications.

About the Customer

The customer’s regulatory portfolio consisted of approximately 10 interconnected systems handling certifications covering both professional certifications as well as equipment registrations. While serving millions of people globally, the internal processing systems are utilized by fewer than 100 examiners, indexers, and supervisors who review and approve certification applications.

Customer Challenge

The certification system operated on legacy mainframe technology using the Software AG Natural programming language and ADABAS databases. It integrated with multiple systems including an external application submission portal, document management relying on screen scraping, and a portal where individuals manage their certifications.

Moreover, documentation of business rules was limited, making maintenance and enhancement difficult. Integration required manually keyed information from digitized documents. Additionally, recruiting developers with mainframe skills was increasingly difficult, threatening long-term system sustainability.

Partner Solution

The solution architecture utilizes Java for backend services and Angular with Angular Material for the frontend. The customer selected AWS for its proven reliability with mission-critical government systems and compliance with federal security standards.

System Consolidation and Modernization

Karsun consolidated two mainframe subsystems eliminating complex inter-system communication mechanisms. The team replaced legacy screen-scraping interfaces with RESTful APIs. This enabled real-time data exchange and eliminated brittle integration points.

Document Workflow Reimagined

Rather than simply replicating mainframe processes, Karsun reimagined workflows for the cloud environment. The new system retrieves only essential metadata from the document management system while maintaining secure access to document images. Karsun implemented automated processing for routine certification types eliminating unnecessary manual review and streamlining operations.

Requirements Validation Approach

Given the minimal documentation, Karsun established a rigorous requirements validation process. It worked closely with the mainframe sustainment team to analyze mainframe code and database schemas. Working with the customer, the team documented findings and confirmed functionalities. Requirements were captured as user stories with acceptance criteria following agile best practices, ensuring business approval at each increment.

Karsun introduced its ReDuX platform. This AI-powered platform for legacy code analysis accelerates discovery and delivery of complex modernization initiatives. Its parser ingests Natural mainframe code and creates comprehensive system blueprints. Using ReDuX the team validated business rules and identified edge cases often overlooked during traditional requirements gathering.

Get started at GoReDuX.ai.

As agencies such as the Internal Revenue Service shrink workforces and adopt leaner operational models, resources to support large scale modernization efforts are increasingly constrained. It is under this strain that John Gilroy opens a recent episode of the Federal Tech Podcast recorded live at the AWS Summit in Washington, D.C. Karsun Co-Founder Kartik Mecheri joins John and former General Services Federal Acquisition Services (GSA FAS) Commissioner Alan Thomas for a discussion on AI, digital workforces and the future of government modernization.

As John observes, the landscape of federal technology is at a critical juncture. Imagine systems born in the 1960s, like COBOL, still running essential government operations, while the average federal worker was born almost two decades later! This generational gap, combined with a shrinking government workforce creates an undeniable need for modernization.

At the same time, government agencies face immense pressure to deliver better experiences for their customers while grappling with complex legacy systems and processes that have been perfected over decades. These systems, often mainframes, are not just old; they are mission-critical, meaning they cannot be simply turned off for upgrades. Modernizing them is, as John notes, akin to “doing a little upgrade while you’re flying the plane”.

The AI Imperative: Introducing ReDuX AI-Powered Modernization

Enter Artificial Intelligence, AI. Government agencies are increasingly interested in AI for modernization to pick up the slack from fewer personnel and improve service delivery. Karsun Solutions offers a powerful tool designed specifically for this challenge: ReDuX.

The ReDuX Modernization Platform Addresses Several Key Pain Points:

• Declining Subject Matter Expertise: As veteran employees retire, the deep knowledge of these legacy systems often walks out the door with them. Redux.ai aims to capture this expertise.
• Complex Migrations: Converting decades of intricate code and interactions into modern architectures within a tight timeframe (e.g., 40 years of work into a 5-year project) is a monumental task.

How ReDuX Transforms Modernization

Redux uses specialized AI agents to streamline the modernization process:

• Blueprinting Agents: These agents delve into legacy code, extract crucial information, and integrate it with user guides and demonstrations. The goal is for the agents to become the subject matter expert on the legacy system.
• Modernization Agents: Once the legacy system is understood, these agents can convert the code to run on modern cloud platforms like AWS or Azure. They ensure the new system adheres to the required architecture and security posture of the agency.

Karsun has successfully used ReDuX to migrate multiple mainframe COBOL applications and other legacy systems (like Visual Basic 6, VB6) to modern technologies. This approach can accelerate modernization by 4x and reduce costs by 2x, reducing key modernization tasks by months and even years.

The Rise of the Digital Workforce

A key concept driving this transformation is the “digital workforce”. This involves building digital equivalents or “digital assistants” for every role in the software development cycle. Imagine:

• An architect agent that understands your target architecture and generates diagrams, documentation, and security architecture.
• Agents for creating unit tests, generating code, or ensuring security compliance.
• Agents for business analysts to create user stories.

The idea is to empower agile teams with digital support allowing them to focus on strategic, high-value, creative, and innovative work. While managing human teams is a well-understood skill, managing these “agents” is a new frontier that the future leaders will need to master.

Looking ahead, experts predict that within a year, we will see more demonstrable examples of AI deployment with clear business benefits. Leaders will need to balance AI’s promise with risks. As they conclude their discussion, John, Kartik and Alan discuss strategies for mitigating AI hallucinations, improving accuracy and reducing security risks. They also discuss identifying technology partners with the strategic relationships required to effectively implement technology in the evolving environment.
For federal legacy systems the modernization journey is complex, but with innovations like Karsun Solutions and the ReDuX team, the path to a more efficient, agile, and secure government future is becoming clearer.

At Karsun Solutions, we’re constantly pushing the boundaries of innovation, especially when it comes to modernizing legacy systems. Our monthly Innovation Town Halls showcase how our experts use emerging technologies like automation and AI to solve real-world customer challenges. Recently, we had two insightful presentations that highlighted the power and versatility of our ReDuX AI-powered modernization platform in transforming complex legacy code using an AI code parser. That team recently summarized their findings on our GoReDuX Blog. Today we’re sharing their insights below.

Natural/ADABAS Modernization with ReDuX AI Code Parser

A common pain point for mainframe customers involves systems written in legacy Natural code with ADABAS. The desire to move away from these systems is driven by several factors, including proprietary software costs, workforce shortages and the fine-tuning required for proper system performance. 

While other modernization tools offer automations for refactoring or replatforming, they often fall short in providing deeper insights. Moreover, they do not lay the groundwork for future enhancements.

The ReDuX Solution

Karsun expert Eamon Cusic shared how his team addressed this. Using ReDuX, they developed a Natural parser capable of assessing both the syntax and semantic structure of the code The team utilized ReDuX Blueprinting agents to analyze user behavior, software module code, and VSAM database schema.

This enabled them to provide context within the VSAM, including crucial elements like core business logic, data flow, and screen flows. With ReDuX Blueprint citations, Eamon’s team could even examine exact window management subroutines, providing unprecedented clarity.

Conquering VB6 and Unsupported Third-Party Components

Raminder Saluja, an AI for modernization leader in our aviation practice, shared another critical challenge facing his customer. A vital legacy application faced obsolescence because its language and third-party components were no longer supported, making modifications and bug fixes nearly impossible. The looming threat? The application was anticipated to stop working with the next Windows update.

The ReDuX Solution

Raminder’s team needed a tool for rapid modernization. ReDuX proved to be the solution, not only capable of parsing VB6 code but also validating requirements and generating test cases as part of the modernization process. After leveraging the Blueprinting agents (like those used for Natural), Raminder’s team extended ReDuX’s VB6 parsing to its code companion code generation agent. The ultimate goal: migrate VB6 to a VB .Net application.

This approach dramatically reduced the modernization timeline. While traditional methods can take over a year, this ReDuX-powered effort is expected to be completed within a 6-month timeframe.

ReDuX: A Mature Framework for Any Legacy Language

What these case studies demonstrate is ReDuX’s incredible adaptability. Whether you’re dealing with Natural, VB6, Oracle Forms/Apex, or other legacy coding languages like COBOL, ReDuX provides a mature framework that allows for the addition of new parsers and libraries. Depending on the language’s complexity, a ReDuX AI engineering team can typically write new parsers in just 2-6 weeks.

Both Eamon and Raminder leveraged this mature process to tackle previously intractable code parsing problems, transforming challenging modernization efforts into achievable projects.
