Modernization as a Service for Legacy Software Applications

Unlock the future of your legacy estate



Transforming legacy modernization services

Many organizations are eager to transform legacy applications from outdated technologies into modern, cloud-native platforms securely, reliably and at scale. To that end, they require an outcome-based approach to legacy application modernization services, combining advanced AI, proven engineering expertise and a transparent pricing model to deliver business value from day one to support their business goals.


Modernization that pays its way

Modernization as a Service (MaaS) is DXC's answer to the transformation programs that consume budgets and deliver marginal results. MaaS combines AI-assisted code conversion, cloud-native re-architecture and outcome-based delivery into a managed model that helps you generate revenue, not just retire technical debt.

Traditional core transformation is a multi-year, high-risk program with a binary outcome. MaaS breaks that model. Modernization is phased, continuous and commercially structured so that each milestone delivers measurable value before the next begins. The result: a faster path to modern architecture, lower program risk and a recurring revenue structure that aligns DXC's incentives with yours.



How Modernization as a Service works

AI-assisted legacy code conversion

Our expert engineers use automated tools and AI to reverse engineer legacy COBOL and proprietary codebases, extract specifications and map dependencies, combining automated and manual conversion to ensure functional parity and business logic fidelity.

Core transformation

Modernization doesn't have to mean disruption. Our phased migration approach keeps your live systems running as we progressively transform your estate, so the business stays operational while the future is being built beneath it.

From traditional tooling to AI-driven technology

Our Recursive AI Method (RAM) combines generative AI with human-in-the-loop validation, delivering a 3x acceleration of modernization timelines without compromising quality, governance or business logic fidelity. What once required years of consultant-led mapping can now be completed in quarters.

Outcome-based delivery

Milestones tied to business results, not billable hours. We take on the complexity and risk of modernization so you can move forward with confidence,  predictable costs, minimized disruption and a clear path to transformation.

Start with Modernization Express

Not every modernization program needs to begin with a multi-year roadmap. For organizations that want a proven, low-risk entry point, Modernization Express is a fixed-price, fixed-scope engagement that delivers a defined outcome in just 90 days. 

The engagement runs across four stages. DXC works with your team to define scope and establish secure access to the relevant codebase. Conversion is then carried out using our Recursive AI Method, with your engineers able to observe progress throughout. The converted Java is validated for functional equivalence before handover, and the final output is production-ready code built for a modern, cloud-native architecture. Every stage has clear entry and exit criteria, so there are no ambiguities about what has been delivered and what comes next.


Why choose DXC to transition from legacy to modern platforms?

DXC helps enterprises modernize a wide range of legacy platforms and languages, including mainframe, COBOL, PL/I, Assembler and RPG. Whether you’re in financial services, insurance, public sector or another industry, our legacy system modernization services offering is tailored to your unique needs and requirements for operational efficiency, business growth and digital transformation.

The pressure to act is real. More than 60% of COBOL developers are over 55, and as institutional knowledge retires with them, systems become harder to document, harder to change and harder to defend. Organizations that delay modernization don't just accumulate technical debt, they lose the people who understand what the code actually does.

Renovating legacy modernization services doesn't have to be complex. DXC guides you through all the steps, aided by AI and knowledgeable experts:

  • End-to-end delivery: from initial assessment to production launch and ongoing optimization to stay competitive

  • AI-powered acceleration: generative AI and automation to speed up analysis, conversion and testing in your modernization journey

  • Human+ validation: technically expert and experienced engineers who ensure compliance, quality and business logic fidelity

  • Transparent pricing: predictable costs with our line of code (LoC pricing) model

  • Proven results: billions of lines of code modernized, thousands of successful transformations and industry-leading reliability

Frequently asked questions

Modernization as a Service by DXC is an outcome-based, tiered offering that enables organizations to convert legacy applications into modern, cloud-ready solutions to support business growth. Unlike traditional project-based legacy application modernization solution approaches, our legacy system modernization services provide a structured journey from initial assessment and blueprinting, through code analysis and conversion, to re-engineering, DevOps integration and ongoing optimization to help future-proof your environment. Our technology modernization service leverages advanced AI, automated tooling and deep human expertise to deliver predictable results, reduce risk and accelerate time to value.

Our solution is designed to support digital transformation for a wide range of legacy systems, including mainframe platforms, distributed applications and midrange environments. Our legacy modernization services specialize in modernizing languages such as COBOL, PL/I, Assembler, RPG and Natural, as well as complex, business-critical existing applications and systems found in financial services and modernization strategies, insurance and the public sector. With our approach to software modernization services, we ensure that even the most challenging legacy estates can be transformed into modern, cloud-native platforms, unlocking agility, scalability, operational and business efficiency, and long-term value for your organization.

DXC uses a transparent line-of-code (LoC) pricing model, meaning you pay per line of code modernized, with rates adjusted for the volume and complexity of your estate, opening the door to cost savings. DXC takes on the risk by committing to the outcome with this cost-efficient approach that ensures simplicity and scalability, whether you are modernizing a single application or an entire portfolio to support your business needs. Our pricing tiers account for factors such as source language complexity and existing documentation, and we offer a fixed-price assessment to help you understand your options before committing. This model gives you confidence in budgeting and planning the right strategy for your modernization journey.
