What is a Legacy Application?
In order to understand how to deal with legacy applications, it’s important to first understand what they are. In simple terms, a legacy application refers to any software system that is outdated but still crucial to the operation of a business. These applications were typically built using older technologies, often decades ago, and may have been designed to meet the specific needs of the time.
These legacy systems are often deeply embedded within an organization’s operations, sometimes forming the backbone of critical business processes because of how old they are, emphasizing the need for legacy application modernization services.
Despite their huge importance, many of these legacy systems face significant challenges such as poor scalability, high maintenance costs, security risks, and an inability to integrate with modern tools and platforms which cause a lot of issues along the way.
Research by Atera found that businesses spend up to 80% of their IT budget just on maintaining their legacy systems. The resources spent on keeping these outdated systems functional could be better utilized for innovation and development of new products or services.
Even though they have outdated technologies, legacy applications continue to be pivotal for many organizations, and organizations are reluctant to abandon them entirely due to the heavy investment already made in their development, maintenance, and integration with other systems.
Many companies believe that it would be a waste of resources to get rid of these systems after investing that much time, energy, and effort in them. This is where legacy application modernization services come into play; they work as a middle-ground in order to prevent great financial losses while preserving the importance of these legacy systems.
What is Legacy Application Modernization?
Legacy application modernization is the process of updating and transforming outdated software systems to leverage modern technologies, improve performance, and align with current business needs.
The goal is to ensure that the legacy software can integrate with cloud platforms, enhance security, meet compliance requirements, improve user experiences, and reduce ongoing maintenance costs.
According to a report by Gartner, more than 50% of IT budgets are expected to be dedicated to modernization initiatives by 2025, focusing primarily on legacy application modernization services. This highlights that businesses are recognizing the need to update their old systems to align with modern technology, which can bring long-term cost savings and performance benefits.
Why Modernize Legacy Applications?
The question of why choose legacy application modernization services is essential for any organization considering a change. Modernizing legacy applications isn’t just about replacing old software, it’s also about addressing the challenges that come with these legacy systems and improving business operations. Below are key reasons why we think you must consider modernizing legacy apps:
- Inability to Scale
Because legacy applications are often not designed with scalability in mind, businesses grow, and the demands placed on these applications increase, and outdated systems struggle to keep up with higher volumes of data, traffic, or user interactions.
Using legacy application modernization services often includes moving them to more scalable platforms that can automatically adjust to increasing workloads without significant manual intervention.
- Security Vulnerabilities
Cyber threats are becoming an increasing concern, and security must always be a top priority for all businesses. Many legacy applications were developed at a time when security wasn’t as strong or when the risk of cyberattacks was less likely to happen.
As a result, these systems often have security vulnerabilities due to outdated encryption methods, weak authentication protocols, or flaws that hackers can exploit which could end up in great losses for the company.
With legacy application modernization services, organizations can improve security with modern features such as encryption, multi-factor authentication, and regular security updates to protect sensitive data from breaches and theft.
- High Maintenance and Operational Costs
While legacy applications may continue to perform their core functions, maintaining them can be costly. As technologies evolve, finding developers skilled in older programming languages or frameworks becomes increasingly difficult and costs a lot of money. Also, the specialized software needed to run legacy applications can be expensive to maintain and operate.
Legacy application modernization services can greatly reduce ongoing maintenance costs, as newer applications are more efficient, and organizations can migrate to cost-effective cloud platforms that provide better scalability and lower operational costs.
- Limited Integration with New Technologies
Organizations use a range of modern tools to manage different operations. These might include cloud-based applications, customer relationship management (CRM) systems, or artificial intelligence-driven analytics platforms.
However, legacy applications are often incompatible with these newer technologies. For instance, a legacy inventory management system might not be able to communicate with a modern e-commerce platform.
Legacy application integration is crucial in legacy application modernization services. Integration capabilities enable organizations to leverage data and insights across multiple platforms, aiming to improve decision-making and workflow automation.
- Poor User Experience
User expectations have changed dramatically over the years because of the quick advancements that happen every day. Customers and employees now demand intuitive, fast, and responsive digital experiences.
Legacy applications, often built with old user interfaces, fail to meet these expectations. Slow performance, old designs, and limited functionality can frustrate users, negatively affecting customer satisfaction and employee productivity.
Modernizing legacy applications using legacy application modernization services allows businesses to offer enhanced user experiences, delivering faster load times, mobile compatibility, and an interface that’s more intuitive and user-friendly.
- Compliance and Regulatory Issues
Regulations surrounding data privacy, such as the General Data Protection Regulation (GDPR), and industry-specific standards are constantly evolving. Legacy systems, which may not have been built with compliance in mind, could be at risk of failing to meet these new standards.
The inability to handle compliance requirements could expose the organization to legal liabilities and fines, which leads to huge financial loss. Modernization using legacy application modernization services helps ensure that legacy systems are updated to comply with current and future regulations, reducing the risk of costly fines and damage to the company’s reputation.
Benefits of Legacy Application Modernization
While legacy applications come with its share of challenges, the benefits of modernizing it are substantial. The following are key advantages that businesses can expect from legacy application modernization services:

Best Legacy Application Modernization Strategies
All organizations must choose a modernization strategy based on their unique needs, preferences, goals, and available resources. Some of the most common strategies that companies use include the following:
- Rehost (Lift and Shift)
This strategy is popular in legacy application modernization services and involves moving the legacy application from on-premises hardware to a cloud-based infrastructure without making significant changes to the application’s code. It’s a quick way to achieve some of the benefits of modernization, such as scalability, with minimal effort. However, it does not leverage the full potential of modern technologies.
- Replatform
Similar to rehosting, replatforming involves migrating the legacy system to a more modern platform, often without changing its core functionality. It’s a step beyond rehosting, and it can include updating the database or using more efficient technologies to run the application on a new platform.
- Refactor
Another strategy in the legacy application modernization services is to refactor. It is the process of modifying and improving the internal structure of an application without changing its external behavior. This involves rewriting the code to improve performance, fix bugs, and enable easier future updates. Refactoring helps to modernize the system’s architecture, making it more maintainable and easier to use.
- Rearchitect
Rearchitecting goes beyond refactoring. It involves redesigning the entire application to make it more efficient and aligned with modern business needs. This may include redoing its architecture, replacing outdated components, and even rewriting large portions of the code for a more modern version.
- Replace
There are cases where the legacy system is too complex, costly, or outdated to use legacy application modernization services effectively. Organizations then may opt to completely replace it with a new, off-the-shelf solution. This approach is often used when a business wants to upgrade to a more feature-rich system that meets its current and future needs.
