One of the main challenges that most businesses with applications face is managing and optimizing and improving their existing IT systems, especially legacy applications. Legacy applications are typically older software systems that are still working but may no longer meet the needs of the organization or align with the latest technological advancements because of how fast industries and technologies change.
There are two approaches companies take when managing their legacy applications, application maintenance and application modernization. While both approaches work to ensure that legacy systems continue to serve the business, they work in different ways. So, if you’re confused and don’t know whether to maintain or modernize, this blog is here to help you decide.

Application Maintenance VS Application Modernization
Application maintenance involves keeping existing applications running smoothly and ensuring that they continue to support the day-to-day needs of the business. This approach typically includes tasks such as bug fixes, patching, minor upgrades, performance tuning, and addressing security vulnerabilities before they turn into bigger issues.
However, while it ensures that legacy applications remain operational, it does not address the underlying issues of outdated architecture or compatibility with newer technologies. It is a reactive and short-term solution aimed at keeping the software functional rather than improving it and making it more modern.
Application modernization, on the other hand, refers to the process of transforming legacy applications to modern, scalable, and flexible architectures that meet current and future business needs. This process can involve a range of activities, including rewriting or refactoring code, migrating to cloud-based platforms, re-architecting applications, and integrating new technologies.
Why is App Modernization Important?
If you already understand what is application modernization, it’ll also be important to know its importance and why many businesses choose to modernize their applications. Legacy systems, while still functional, can present significant challenges for organizations. These systems may not be compatible with newer technologies, they may have outdated interfaces, or they may be prone to security vulnerabilities. Moreover, the cost of maintaining these applications can become very expensive over time.
According to a 2023 report by McKinsey, 65% of IT leaders identified legacy applications as one of the biggest barriers to digital transformation. This is mainly due to the fact that legacy systems often have limited scalability, lack integration with newer applications, and struggle to meet the demands of modern business processes, making working with them hard and time consuming.
In addition, Atera research also found that “up to 80% of companies’ IT budgets is spent keeping old IT systems afloat,” and “40% of IT leaders regret their legacy technology purchases.” Because of all of this, many companies have decided to shift to application modernization instead of getting rid of the legacy system altogether.
Differences Between Application Maintenance and Application Modernization
There are a few main differences that you must keep in mind while choosing. We’ve gathered these differences for you down below:
- Purpose and Scope
The primary difference between application maintenance and modernization lies in their purpose and scope. With app maintenance, the main focus is on keeping legacy applications operational without making significant changes to the underlying architecture or adding new features. Maintenance ensures the application continues to perform as expected but doesn’t address any fundamental issues with the software.
With application modernization, the focus is on improving the legacy application by transforming it into a more modern version. Modernization often involves substantial changes to the architecture and platform, making it more scalable, secure, and compatible with modern technologies.
- Time and Effort
Application maintenance is generally less time-consuming and may only require minimal resources compared to modernization. It is more about keeping the lights on and ensuring the application doesn’t break down or cause downtime.
Modernization is a different story; it is a more resource-intensive process that requires careful planning, skilled personnel, and a longer time commitment. This process may take several months or even years, depending on the complexity of the legacy system and the goals of the organization.
- Cost
The cost of maintaining legacy systems is often more predictable but can accumulate over time. As legacy systems become more complex and less efficient, the cost of maintenance tends to increase.
However, while application modernization requires a higher upfront investment, it can result in significant cost savings in the long term. By moving to more efficient, cloud-based platforms and streamlining operations, businesses can reduce ongoing maintenance costs and improve the performance of their systems, meaning that they won’t have to spend that much money in the long run.
- Business Impact
Application maintenance focuses on keeping the business running smoothly in the short term but may not address the need for digital transformation or innovation. It can prevent immediate disruptions but may not enable the business to grow or adapt to new challenges.
On the other hand, application modernization provides long-term benefits by enabling businesses to innovate, improve customer experiences, and take advantage of new technologies. A modernized application is more flexible, adaptable, and better aligned with business goals.
How to Decide Between Application Maintenance and Modernization
Deciding between app maintenance and modernization requires careful consideration of several factors. Both approaches have distinct benefits and challenges, and the choice between them can significantly impact your IT strategy, resources, and long-term business outcomes.
We understand that the decision isn’t always straightforward; businesses must carefully evaluate several factors before determining which path is best suited to their current and future needs. This is why we’ve gathered various considerations, from business goals to the specific challenges of the legacy system for you to consider down below:
- Assess Your Business Goals and Strategy
The first step in deciding whether to choose application maintenance or modernization is understanding your broader business goals and IT strategy. First, ask yourself what your strategic priorities are. It’s important to know whether you’re focused on cost savings and maintaining the status quo or if you are aiming to drive innovation and improve your customer experience.
Second, decide the importance of the legacy system you have to your business operations. If the legacy system is integral to your operations and customer-facing services, you may need to prioritize application modernization to avoid obsolescence. Alternatively, if it’s more of a back-office system with limited user interaction, maintenance might be sufficient in the short term.
- Evaluate the Condition of the Legacy System
The condition of your legacy system plays a crucial role in determining whether to continue with maintenance or to shift to application modernization. You should conduct a comprehensive system assessment to understand the current state of your application.
If your system is very old, it can be difficult to maintain and integrate with modern solutions and it may be challenging to scale or update it efficiently. If it’s a relatively newer legacy system built on more flexible platforms, it may still have more useful life and be easier to maintain.
Over time, legacy applications can accumulate substantial technical debt that requires more and more resources to manage, even with application maintenance. If your legacy system has become too difficult to upgrade or scale, modernizing legacy apps can help eliminate that debt and future-proof your IT infrastructure.
It’s also important to know if your legacy system is struggling to meet growing business demands. If the legacy system is unable to handle increasing data volumes, user loads, or more complex business processes, application modernization can improve its scalability and performance, often with significant cost and operational benefits. On the other hand, if performance is still adequate, maintenance may be enough to keep the system running smoothly for a while longer.
- Understand Your Budget and Resource Constraints
One of the most significant factors in choosing between application maintenance and application modernization is the available budget and resources. Modernizing an application is typically a costly and time-consuming process, which might require large investments in both technology and human resources.
If the cost of modernization exceeds your current budget, it might be a good idea to opt for legacy app maintenance until you can afford the necessary investment.
- Evaluate Long-Term Business and Technological Needs
Even if your current legacy system is still functional and cost-effective, it’s crucial to consider the long-term plan of your business and technological needs. Legacy applications were built for a different time and may not be able to evolve quickly enough to support future business strategies.
It’s also important to consider your customer base. Modern consumers demand better experiences, faster services, and enhanced security. Application modernization helps you meet these evolving customer expectations by improving functionality, enabling self-service capabilities, and ensuring high availability and security. Legacy apps, on the other hand, may be slow, leading to customer dissatisfaction.
- Assess How Much Innovation Your Business Needs
Another factor to consider when deciding between application maintenance and application modernization is the level of customization and innovation that your business requires.
If your legacy system is still functional and can support your current operations, but you don’t need much in terms of innovation, maintenance might be sufficient. App maintenance ensures that the system continues running smoothly, fixing bugs, applying patches, and handling minor upgrades, but without introducing significant changes or new features.
On the other hand, if your business requires customization to meet new needs or is seeking to innovate in areas, modernization is the way to go. By transforming legacy apps into modern architectures, you can integrate new features and enhance the user interface and user experience.
