Driving Legacy Code Modernization: The Path Forward with Strategic Partnerships and an AI Future

We don’t believe in one-size-fits-all solutions because we know your business has unique challenges and goals. That’s why, with a track record proven through projects like our Federal Government modernization case study, we offer co-development opportunities that allow us to craft a customized modernization journey just for you.

The Case for Legacy Code Modernization

If your business is still relying on systems that were built decades ago, you’ve probably experienced firsthand how frustrating it can be when outdated technology holds you back. You might feel stuck like you’re trying to run a race with weights on your ankles. We get it. Legacy systems can be unreliable, costly to maintain, and worse—they can leave you vulnerable to security risks.

Let’s break it down a bit:

• Security Vulnerabilities: We’ve all seen the headlines about data breaches. The older your systems, the harder it is to keep them secure against today’s sophisticated cyber threats. Applying patches and updates to legacy systems can feel like plugging holes in a sinking ship—ineffective and expensive.
• High Operational Costs: In particular, COBOL systems are becoming increasingly costly to maintain. The experts who know this language are retiring, and finding new talent is like searching for a needle in a haystack. This dwindling talent pool means operational costs continue to rise, leaving you with an expensive problem that only gets bigger with time.
• Integration and Scalability Limitations: Your legacy system wasn’t designed to play nicely with cloud environments or the modern API-driven world. As your business grows, you’re probably finding it harder to integrate new technologies and scale up to meet market demands.

We know this sounds tough, but here’s the good news: modernization offers solutions that can unlock incredible opportunities for your business. By embracing a modernized system, you’re not just solving problems, you’re positioning your business to thrive in today’s fast-paced, technology-driven world.

• Improved Agility and Operational Resilience: When you refactor legacy code, you’re setting your business up for success by adopting modular, service-oriented designs. This boosts your ability to pivot quickly and adapt to new challenges.
• Long-Term Cost Savings and Cloud-Readiness: Modernization isn’t just a short-term fix; it’s a long-term investment. By moving to cloud-ready platforms, you eliminate those hefty infrastructure costs and leverage the flexibility of the cloud.
• Enhanced Security and Compliance: Say goodbye to sleepless nights worrying about cyber threats. Modern systems come equipped with the latest security protocols, making compliance with industry regulations easier and giving you peace of mind.

ROI reports for legacy modernization show promising results. Forrester’s analysis of modernization initiatives found a 228% ROI over three years when using Azure Platform-as-a-Service (PaaS), with a payback period of 15 months. Benefits included a 50% increase in the speed of app development and a 40% reduction in infrastructure costs​. In another study commissioned by OpenLegacy revealed a 353% ROI over three years, driven by reduced integration costs, faster time-to-market, and improved productivity through automated development processes​.

Of course, we recognize that on some modernization journeys, customers will acknowledge that certain components of legacy systems will continue meeting business needs, thereby making these components good candidates for our legacy code refactoring processes. Ongoing modernization efforts may also include implementing certain Commercial-Off-the-Shelf (COTS) tools or components as ancillary systems to improve the overall infrastructure. This approach helps achieve the modernization objectives and address security and other challenges.

• Structured Data Types and Fixed Formats: COBOL’s structured data types and fixed formats require precise handling, making established cross-compilation solutions essential in ensuring accurate translation and performance preservation during modernization.
• Legacy Business Logic: COBOL systems often have deeply embedded business rules that have evolved over decades. To accurately reengineer these systems, we need to understand the ‘why’ behind the code, not just the ‘what.’
• Global Variables and Common Areas: COBOL uses global variables that are scattered throughout the code, making modularization and refactoring an uphill battle.
• Procedural Paradigm and Lack of Modularity: Most COBOL code is monolithic and procedural, meaning we need to break it down and rebuild it as object-oriented, modular code to meet today’s standards.
• Documentation and Knowledge Gaps: Let’s face it—COBOL systems are old, and the people who built them may have left the company years ago. Documentation is often entirely unavailable, scarce, or outdated, making it a challenge to fully understand the system without expert analysis.

Enterprise Iron’s Modernization Approach

At Enterprise Iron, we see your legacy systems as more than just old code. They tell the story of your business, and every modernization journey we craft is tailored to respect that story. We bring a human touch, combined with cutting-edge automation and agile methodologies, to ensure your modernization process is smooth, efficient, and most importantly, effective.

1. Initiation and Planning
When we first sit down with you, we start by listening. We want to understand your system, your business, and your goals. From there, we dive into an in-depth assessment of your legacy system to identify critical components, business logic, and dependencies.
Together, we define a modernization strategy that fits your needs, from cloud migration to code re-engineering. We also outline how automation tools and human engineering will play a role in the process, always making sure you know what to expect at every step.

2. Development and Conversion Workload Assignment
Our engineers leverage conventional cross-compilation tools to manage complex code parsing and conversion into modern languages like Java. This method effectively addresses large-scale transformations while maintaining accuracy and alignment with the original business logic. The beauty of this approach is that if selected, automation handles the simple stuff, leaving our human experts free to focus on the complex, nuanced parts of the code that need that personal touch. Sometimes, between 60%-90% of the code can be handled by automation, with improvement seen over sprints, but the final polish always comes from human hands.

3. Integration and Continuous Delivery (CI/CD)
Once we’ve modernized your code, it’s time to integrate it into your existing system. We run regular tests to make sure everything works seamlessly and doesn’t disrupt any current functionality. You won’t be flying blind—we continuously monitor the integration for any potential issues, ensuring a smooth transition.

4. Quality Assurance and Performance Testing
Before we flip the switch and fully deploy the new system, we make sure everything works perfectly under real-world conditions. We run both functional and non-functional tests, including performance, regression, and parallel system tests, to make sure the modernized system behaves just like the legacy one—only better. We also prioritize mission-critical processes for additional manual validation to ensure your business runs smoothly.
This process, the conventional and/or more modern AI tools employed are a Modernization Framework that we initiate, use, and optimize during our partnerships, and then leave behind as a modernization framework for continuing your modernization journey.

2. Compliance Risks: Legacy systems often struggle to meet evolving regulatory requirements (e.g., GDPR, HIPAA, and PCI-DSS). Inadequate logging, auditing, or encryption practices can result in compliance failures and potential penalties.
3. Data Integrity: As data migrates from legacy systems to modernized platforms, ensuring data integrity is critical. The risk of data loss or corruption is heightened during this process, especially when data formats and architectures differ significantly.
4. Access Controls and Authentication: Legacy systems typically lack advanced access controls, making it difficult to enforce granular permissioning, multi-factor authentication (MFA), and secure user management.
5. Encryption and Data Protection: Legacy systems often have insufficient or outdated encryption protocols, increasing the risk of data exposure, both at rest and in transit.

Our Security Methodology and Tools

To address these critical security concerns, our methodology involves a multi-layered approach that includes:

1. Local AI Deployment: When AI is part of the solution, we prioritize local deployment of AI models, which ensures that sensitive code and data remain within a corporate-controlled environment. This reduces the risk of data exposure during processing and aligns with zero-trust architecture principles.
2. Advanced Access Controls: We implement robust role-based access controls (RBAC), integrating MFA to ensure that only authorized users can access sensitive functions and data. Our solutions support identity and access management (IAM) tools, allowing seamless integration with existing security protocols.
3. Strong Encryption Protocols: We enforce modern encryption standards, like AES-256 for data at rest and TLS 1.2/1.3 for data in transit. This protects against data interception and ensures compliance with regulatory requirements across industries.
4. Secure Data Migration: During data transitions, we use end-to-end encryption and employ secure migration tools that maintain data integrity. We perform validation checks at each stage of migration to ensure data accuracy and completeness, reducing the risk of data loss or corruption.
5. Compliance and Audit Readiness: Our solutions include built-in logging, monitoring, and reporting features that ensure compliance with relevant regulations. These features support regular audits and simplify reporting requirements, reducing the effort required for compliance validation.
6. Continuous Monitoring and Threat Detection: Our modernization process includes implementing security monitoring tools for proactive threat detection. This enables real-time alerts and rapid response to potential breaches or anomalies, keeping your data protected throughout the modernization journey.

By applying this comprehensive security framework, we ensure that your modernization efforts not only align with best practices but also enhance your organization’s security posture against both existing and emerging threats.

Collaborative Modernization: Partnering with Clients

We believe that modernization is a partnership. No one knows your system better than you, and no one knows modernization better than us. By working together, we can ensure a successful outcome.

• Pilot Programs: We often start with a pilot program that lets you see the benefits of modernization firsthand without diving in headfirst. This builds momentum and confidence as we move forward together.
• Tailored Modernization Process: Every step of the way, we tailor our approach to your unique requirements. This isn’t a cookie-cutter process, it’s a journey that’s designed just for you. This process employs a comprehensive modernization framework that combines both proven cross-compilation tools and advanced AI capabilities, ensuring a balanced and effective modernization journey.

Case Study: Federal Government Legacy Modernization

One of our proudest success stories comes from our work with a Federal Government agency that was stuck in a challenging situation. Their legacy system had been trans-compiled into ‘JOBOL’ — a form of COBOL that was previously converted to Java but was characterized by reduced maintainability compared to best-practices Java and was dependent on libraries that tightly couple the code to vendor-proprietary, licensed components. This setup created barriers to long-term goals, and that’s where we came in.

Working side by side with the client, we used an agile approach over 12 sprints to modernize and refactor their system into a modern object-oriented Java solution that was independent of their JOBOL libraries. What set this project apart was our collaborative approach—every sprint involved client feedback, ensuring that the final product was exactly what they needed. We re-engineered copybooks to handle I/O operations more efficiently and tackled some of the legacy system’s most inefficient code with care and precision.

The result? A scalable, maintainable system that aligned perfectly with the client’s long-term goals. And better yet, we left them with a repeatable modernization framework they could use for ongoing modernization objectives.

Balancing Innovation with Reliability: Risks and Mitigation

We understand that modernization comes with risks, especially if AI is selected. But we also know how to mitigate those risks. By being transparent about the capabilities and limitations of AI and ensuring that our human experts review everything AI generates, we can balance innovation with reliability.
We use a proof-of-concept phase to test solutions on a smaller scale, run parallel systems during the rollout, and conduct comprehensive testing to ensure functionality. And we always have contingency plans tailored to your needs to mitigate any potential disruptions.

Long-Term Reliability and Scalability

Our modernization approach focuses on creating systems that will serve your business for years to come. With modular designs, service-oriented architectures, and cloud-native capabilities, you’ll have a system that’s not only scalable but also easy to maintain as your business grows and evolves.
