Mainframe Archives

Every program office running a legacy system is on a clock it did not set. The people who know why the code does what it does are retiring, and most of what they know was never written down or if it was, is now out of date. The rules are still there, encoded in the system itself. What is disappearing is the ability to read them.

The Software Acquisition Pathway (SWP) asks teams to value working software over comprehensive documentation. Yet, documentation is what survives to accelerate the work of future teams, and it is the first thing deferred when delivery is the measure. A program can deliver on cadence for years, and still arrive at a system that no one remaining can explain, secure, or re-compete.

The question is not whether to document. It is whether understanding a system still has to cost what it used to.

What the SWP Requires

Under DoD Instruction 5000.87, the pathway establishes the artifacts a program produces to move from one iteration to the next. Those artifacts are what let subsequent teams secure, maintain, and enhance the software after the current team is gone.

Rather than collecting the artifacts from the people who remember the system, teams can now derive them from the system itself. Karsun’s ReDuX analyzes the codebase and generates the underlying material for these documents with citations back to the specific code that governs each one. The citation is the part that matters. It means an assertion about the system can be checked against the system, by anyone.

Dynamically Generate Requirements

One of the first steps in the pathway is capturing the overarching requirements that feed a Capability Needs Statement (CNS) or User Agreement (UA) or other similar document. As ReDuX analyzes user demos and the codebase, it produces requirements and user flows, each citing the specific legacy code that governs it. The requirements are written as behavior-driven given-when-then (GWTs) statements, a form that is testable by agents and reviewable by the developers and subject matter experts who validate them. Because each statement traces to the source code that produced it, any reviewer can confirm it, not only the teams that were there when the system was built.

Architecture Documents

A Software Acquisition Strategy (SAS) requires documentation of both the legacy architecture and the target. The legacy half is where programs get stuck. The available diagrams were drawn years ago and have drifted from what is actually running, and the people who could correct them are the same people who are leaving. ReDuX Blueprinting Lenses derive the legacy picture from the application’s own code and artifacts, covering data and job flows, schemas, endpoints, and screen flows. Because that picture comes from the system rather than from memory, the strategy rests on what the system does today. It is also the precondition for a modular open systems approach (MOSA). Decomposing a system into modules with defined interfaces requires knowing where the seams actually are, and on a legacy system nobody knows that until it is derived.

Scoping, Estimating and Forecasting Work

The same blueprint also changes what a program can see when it plans. Estimating work on a legacy system usually means estimating against an incomplete picture, and the gap shows up later as cost and/or schedule overruns. Working from a dependency map derived from the application itself, teams can find duplicate functionality, sequence enhancements against what actually depends on what, pay down technical debt deliberately rather than opportunistically, and remove dead code with the evidence to prove it is dead. Committing to an annual capability delivery cadence is easier when the commitment rests on the system as it is.

The pathway asks programs to move fast. The clock asks them to move fast without losing what they know. Those pull against each other only if understanding a system still has to come from the people who built it.

Everything described here belongs to the government. The requirements, the architecture, the constraints, and the traceability are platform-neutral and readable without Karsun tooling, which means a program office can hand them to any team, on any target, including a competitor. That is the point. The documentation the pathway asks for should outlast the vendor that helped produce it, and it is worth capturing now, while the people who best understand their legacy systems are still here to ask.

Modernizing legacy applications has become a strategic priority for organizations preparing for AI-driven innovation. However, many organizations hesitate when figuring out how to begin before committing significant resources to changing decades-old systems they may not fully understand.

This is where the AWS Migration Acceleration Program (MAP) can help. MAP reduces both financial and technical barriers. When working with a Migration and Modernization Competency Partner, it provides funding and guidance to assess, mobilize and modernize with greater confidence. And, for organizations considering a ReDuX pilot, MAP provides a way to get started with a focused assessment before committing to a larger modernization effort.

What is AWS MAP?

AWS MAP is a comprehensive cloud migration program that combines proven methodologies, technical guidance, AWS expertise, and funding support to help organizations accelerate modernization initiatives. Rather than expecting organizations to move directly into implementation, MAP follows a phased approach that helps teams understand their environment, build a migration strategy, and execute modernization with reduced risk.

The program is structured around three phases:

Assess – Evaluate existing applications, understand dependencies, identify business value, and determine the best modernization approach.
Mobilize – Build the migration foundation, establish processes, prepare teams, and validate the modernization strategy.
Migrate & Modernize – Execute migration activities and modernize applications using AWS services and best practices.

For many organizations, the most valuable part of MAP is that funding is available even during the early assessment stage, before major modernization work begins. MAP funding is available through AWS Partners, including Karsun, that have achieved the AWS Migration and Modernization Competency.

Why the Assessment Phase Matters

One of the biggest obstacles to modernization is uncertainty. Legacy applications often contain decades of undocumented business logic and institutional knowledge that exists primarily within the code itself. Organizations are understandably reluctant to invest in a large modernization effort without first understanding what they are working with. MAP helps remove that uncertainty.

Through assessment funding, organizations can gain visibility into their applications before making larger investment decisions. Instead of relying on assumptions, teams can evaluate complexity, identify risks, and build a roadmap based on real insights.

This allows decision-makers to answer critical questions such as:

What business rules exist inside the application?
Which systems are tightly coupled?
What should be modernized, retained, consolidated, or retired?
What level of effort should be expected?

Having these answers upfront leads to better planning and significantly reduces modernization risk.

Lowering the Barrier to Getting Started

Since MAP provides funding during the assessment phase, organizations do not have to begin with a large modernization commitment. Instead, they can start with a focused engagement that helps them understand their environment and determine the right path forward.

This approach is especially valuable for organizations considering large-scale legacy transformation. Rather than committing to a full migration immediately, they can validate assumptions, reduce uncertainty, and build executive confidence before moving into implementation.

How Karsun Helps Organizations Maximize MAP

Karsun helps organizations take full advantage of MAP while accelerating modernization with AI-powered insights.

Our AI-powered ReDuX platform naturally aligns with the MAP framework. During the Assess phase, ReDuX creates a comprehensive blueprint of legacy systems by analyzing source code, business logic, application dependencies, APIs, and data relationships. Instead of relying on assumptions, organizations gain a living understanding of how their applications actually operate. This foundation allows teams to make informed modernization decisions before writing new code or beginning migration efforts.

From there, ReDuX supports modernization throughout the remaining MAP journey by helping teams:

Discover and document legacy systems
Preserve critical business logic
Accelerate modernization with AI-assisted workflows
Reduce delivery risk through human-in-the-loop governance

The result is a modernization process that is both more informed and more predictable.

Start with Knowledge, Not Guesswork

Modernization does not have to begin with a leap of faith. With AWS MAP funding, organizations can start by understanding their legacy applications, identifying modernization opportunities, and building a roadmap based on evidence rather than assumptions. By combining AWS’s proven migration framework with Karsun’s AI-powered modernization capabilities, organizations can reduce risk, accelerate decision-making, and move toward modernization with greater confidence. Sometimes the most important step is not migration itself but rather, gaining the clarity to know what comes next.

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.

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.
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.

Tyrion Container Platform

The new system is hosted on Tyrion, Karsun’s Federal Information Security Management Act (FISMA) High-rated AWS GovCloud container platform based on Amazon EKS. The AWS GovCloud’s isolated region is specifically designed for U.S. government workloads providing the security and compliance framework necessary to meet regulatory requirements.

Karsun previously delivered Tyrion as part of a broader transformation initiative for this customer. It provides agency application owners a platform to build, test, deploy, host, and scale container-based software solutions.

The platform leverages multiple AWS services including Amazon EKS for Kubernetes orchestration, Amazon EC2 for compute resources, Amazon Elastic Block Store (EBS) for persistent storage, and Amazon RDS for managed database services. Tyrion’s DevOps ecosystem includes Tekton for build pipelines, ArgoCD implementing GitOps for continuous deployment, Karpenter for intelligent node scaling, Datadog for comprehensive monitoring, Kubecost for consumption apportionment across teams, and Backstage as a developer portal providing self-service capabilities.

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.

Results and Benefits

Certification processing transitioned from mainframe to AWS, delivering measurable business and technical benefits:

Operational Efficiency: Automated processing of routine certifications eliminates manual examiner workload for specific application types, allowing staff to focus on complex cases requiring judgment.
Technical Modernization: API-based integrations replaced screen scraping, improving reliability and reducing integration maintenance. The modern Java and Angular technology stack addresses talent acquisition challenges, with significantly larger developer pools.
Platform Leverage: Deploying on Tyrion provides the application with enterprise-grade container orchestration, automated scaling through Karpenter, comprehensive monitoring via Datadog, and streamlined DevOps workflows through Tekton and ArgoCD. The FISMA High-rated platform eliminates the need for separate security authorization, accelerating time to production.
Knowledge Preservation: Comprehensive documentation created during the project created a sustainable foundation for maintenance and enhancements, addressing the legacy system’s critical documentation gap.

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.

Government agencies facing an increasing mandate to move from legacy mainframe systems. The solution, generative AI. Now, agencies no longer need to fear the tradeoff between migration risk and the opportunity available in the cloud. In this case study featured on the AWS Public Sector Blog, our Karsun experts share their experience accelerating modernization with AI.

This case study features Karsun Solutions’ ReDuX AI powered migration and modernization platform. It offers a compelling approach for enterprises considering mainframe migration. Sharing their experience modernizing legacy applications for one of our government customers, this case study demonstrates what happens when modern AI tools meet modern software development practices.

Deep Insights Using Amazon Bedrock

ReDuX is designed to tackle typical obstacles in mainframe modernization, such as undocumented business rules, technical complexities, and regulatory compliance. Its approach is inspired by Karsun’s decade and a half modernizing complex enterprise systems for the federal government. ReDuX utilizes generative artificial intelligence (GenAI) powered by Amazon Bedrock to analyze and understand legacy systems.

Using Bedrock the Karsun team accessed high-performing foundation models from leading AI companies via a single API. Building their ReDuX platform on top of the resources provided by Bedrock, our team created an AI powered toolkit for identifying and mapping the complex business rules and processes embedded within mainframe applications. This facilitates a smoother transition to modern architectures. Further, by providing a structured approach, ReDuX reduces risks associated with legacy system modernization.

Matching AI with Modern Microservices Architecture

In the case study, we share how using our AI powered platform, we enabled our government customer to migrate from monolithic mainframe systems to microservices-based architectures on AWS.
