Why is legacy modernization so integral to digital transformation success? Digital transformation is a universal phenomenon.
According to McKinsey, nine out of ten surveyed C-suite executives claimed their business had already embarked on a significant digital transformation project. However, not all enterprises are doing it right, and subpar results are becoming increasingly common.
As per Gartner, 65% of board directors claim that they are not on track to achieve digital transformation goals. Legacy software systems and their inability to co-exist with modern digital technologies have a significant role to play in this.
The application and legacy modernization services market highlights the importance of legacy system upgrades. This market will be valued at $32.8 billion in just three years, rising at a compound annual growth rate of almost 17% since 2022. These statistics underline the need for legacy system upgrades and a robust technology modernization strategy.
This article delves into the intricacies of legacy modernization. It answers key questions, including:
Legacy software systems refer to out-of-date IT applications that enterprises still use. It includes software, operating systems (OS), or programming languages that go against contemporary industry best practices and standards. Some primary categories of legacy software systems include software that has reached its scalability limits, overly patched applications, and end-of-life applications.
Legacy software systems are typically unavailable in the market. This means that vendors may not offer any official patches and upgrades. This would also suggest that enterprises have no helpline to reach out to when they face issues.
Additionally, as businesses increasingly take advantage of cutting-edge hardware, legacy software systems will struggle to integrate with this newly commissioned hardware. Another problem with legacy software systems is that modern IT and security teams may lack the knowledge and skills to steward them.
Enterprises may be able to stay afloat using legacy software systems. However, without legacy system upgrades, it’s impossible to make any significant gains in digital transformation. Therefore, legacy modernization is a must.
Legacy modernization involves removing, replacing, or reconfiguring older and out-of-date software. Businesses may be able to decommission specific legacy software systems entirely. Others may have to be upgraded and rendered compatible with modern IT infrastructures.
Legacy software systems can result in compliance failures, cybersecurity incidents, high operational and maintenance costs, and performance bottlenecks. It’s difficult to fix the challenges of legacy applications overnight. This is because legacy software systems are often expensive and difficult to replace. In many cases, they are also the glue that keeps day-to-day business operations functional. Therefore, legacy modernization must be strategically and meticulously executed. It’s essential to approach legacy modernization with a holistic strategy.
Enterprises may choose to deal with their legacy software systems in many different ways. Some may completely replace them, some may decommission them, and some may refactor or reconfigure them to integrate with modern IT infrastructures, ecosystems, and processes. Whichever methods businesses choose to go with, there must be a step-by-step approach to modernizing legacy applications.
The following is a seven-step approach to legacy modernization.
The journey begins with an inclusive strategy session involving key stakeholders across the spectrum – from board directors and C-suite executives to senior IT and security personnel. This collaborative effort is pivotal in crafting a technology modernization strategy that is not just about technology for technology’s sake but is intrinsically linked to the overarching business objectives. This strategy should encompass considerations for digital transformation, cybersecurity, and the potential for leveraging emerging technologies, ensuring that the legacy modernization effort propels the business forward in its market.
Transitioning from strategy to action involves a meticulous inventory analysis. This step goes beyond merely cataloging existing software; it’s about understanding the entire IT ecosystem, including hardware, software, and associated workflows. The aim is to create a holistic view of the technological landscape, highlighting dependencies, potential bottlenecks, and opportunities for integration. This thorough understanding aids in pinpointing critical legacy systems that are ripe for modernization.
Armed with a detailed inventory, businesses must then embark on a process of contrasting their legacy systems against the backdrop of modernization options. This comparative analysis involves evaluating the current state against potential future states, considering factors such as performance enhancements, scalability, security improvements, and alignment with business goals. This step is crucial for developing a clear understanding of the benefits and challenges of different modernization pathways, laying the groundwork for informed decision-making.
With insights gathered from the contrast and compare phase, enterprises can now devise a phased modernization roadmap. This plan should outline a step-by-step approach for transitioning from legacy systems to modern solutions, incorporating testing phases, and setting realistic milestones. The roadmap must be flexible yet structured, allowing for adaptability in the face of technological advancements while ensuring progress is measurable against predefined goals.
The development phase is where strategic plans begin to materialize. Organizations should leverage modern software development methodologies, such as Agile and DevOps, to iteratively develop and refine modernization solutions. Testing these solutions in sandbox environments is critical, allowing teams to identify and resolve issues in a controlled setting, thereby mitigating risks before deployment in live environments.
Implementation marks the transition from planning to action. This step involves deploying modernized systems into the operational environment, which may include migrating to cloud platforms, adopting microservices architectures, containerizing applications, and integrating automation tools. The focus should be on executing the modernization plan with agility, ensuring systems are scalable, resilient, and capable of evolving with the business needs.
Finally, legacy modernization is an ongoing journey rather than a destination. Post-implementation, it’s crucial for businesses to establish mechanisms for continuous monitoring and evaluation of modernized systems. This phase is about measuring performance, user satisfaction, and the overall impact on business objectives. Feedback loops should be created to inform future modernization efforts, ensuring the organization remains agile and responsive to new challenges and opportunities.
By embracing this expanded and enriched approach to legacy application modernization, enterprises can ensure their technology infrastructure is not only current but also strategically aligned with their long-term business objectives, enabling them to navigate the complexities of the digital age with confidence and agility.
Legacy system upgrades result in measurable benefits for organizations. Improved IT performance, easier maintenance, and lower overhead costs are the primary benefits of legacy modernization.
Other significant advantages of legacy modernization include hardened cybersecurity and compliance posture, enhanced scalability, orchestrated workflows, more productive and comfortable IT teams, innovation agility, and more holistic digital transformation.
Robust legacy modernization solutions can greatly help businesses that want to know how to deal with a tech debt. Tech debt is the total of long-term technology-adjacent compromises that an enterprise suffers in exchange for short-term gains. Legacy modernization can pay off tech debts of the past as well as ensure that future tech debts are minimal.

Legacy software systems affect the digital transformation efforts of numerous enterprises. To ensure digital transformation success, businesses must embrace legacy modernization. Legacy modernization is the process of replacing, upgrading, or reconfiguring out-of-date software to enhance IT performance, reduce costs, simplify maintenance, improve digital strength, and boost cybersecurity and compliance.
Legacy modernization includes diverse approaches and techniques. However, a typical legacy modernization process involves seven steps – strategize, inventory, contrast, roadmap, develop, implement, and evaluate. Most importantly, as step 1 of this lifecycle suggests, these activities should strictly abide by a technology modernization strategy that includes business, technology, and security objectives.
