Legacy Integration Challenges and Solutions with Mendix

Fixing your legacy system will never break your business or its revenue. Instead provides stability and functionality to your IT environment through data protection and performance upgrades into cloud technology.

How do you feel about working in Windows XP for your company’s operations in 2023 if asked to?

It might sound obsolete and challenging to handle the XP software as it cannot cope with the latest architecture, protocol, and cybersecurity concerns the digital era poses. So the need to modernise the legacy system rises as software becomes antiquated and difficult to emerge with the latest technologies.

Identifying and integrating legacy systems with modern applications closes the divide between legacy systems and the latest technologies. Through legacy system integration, organizations can seamlessly transfer data and speed interoperability between them. In this regard, you can easily renew your existing software applications and implement the latest technologies for operations without any hustle and bustle.

This blog presents the need for modernization, its challenges, and how to resolve legacy system integration with Mendix Solutions, a low-code platform rapidly evolving in the digital landscape since 2005.

Unveiling the Facts

Explore the repercussions experienced by each organization concerning legacy systems and their integration.

The urgent drive to replace legacy systems for 2022-2024 may call for an investment of $6.3 trillion per IDC 

 An estimation of about USD 2 trillion was spent on technology products, services and staff by the U.S. government in 2022.  

Research suggests that 91% of employees are frustrated with workplace technology and 57% stem from legacy technology.  

Retailers spend nearly 60% of their IT budget on maintaining legacy systems.

Deciding on Modernization: A Practical Perspective

Before undertaking legacy system integration, a comprehensive evaluation of software libraries, protocol components, code behavior, and compatibility with modern technologies is imperative.

Slow responsiveness, data vulnerabilities, or insufficient data processing capabilities persist; it is incumbent upon your organization to upgrade your existing infrastructure. The following reasons ensure you move to modernization at the earliest.

High Maintenance Support  

The older the version of the legacy system, the more difficult it is to maintain, as the functionality becomes slow and monotonous resulting in poor performance. The cost spent on hardware exchange, skilled personnel and vendor support is higher than the benefit you can yield. So an outdated application means increased maintenance cost and less operational value.

Inflexible to Adapt

As mentioned earlier, the major drawback of legacy systems is the inability to connect with new applications and transfer data securely to the latest technology. This can hinder your business for not rapidly responding to new technologies, thereby creating a setback for your business and reputation.

The threat of Cyberattacks

The legacy systems have limited data security audits and mechanisms that do not help with security breaches and unauthorized access in this digital era. It may lead to a hacking marathon if required authentication and configuration are unavailable. Avoid phishing attacks, as your customers trust you with their sensitive data and access.

Data Silos Systems 

Isolated and disconnected legacy systems data have limited accessibility and visibility, unlike cloud and other modern applications. Data silos obstruct a seamless flow of data and integration, so data-driven strategy and informed decision-making are critical in legacy system integration.

Rise of Spaghetti Code

Maintaining a legacy system over time results in damaged and unstructured data that resemble spaghetti. For example, software implemented a decade ago would have undergone numerous unhealthy coding practices that may not be relevant, creating a tangled and interconnected plate of spaghetti code that is hard to understand and recover.

Breaking Down the Challenges on the Path to Legacy System Integration

As you are ready to work on the legacy system integration for interoperability and seamless data transfer, the journey towards modernization is not a shift of job that can be done easily.  Infer the following challenges blocking your business operations from leveraging modern technology and solutions.

Lack of Documentation

Without comprehensive documentation, deciphering code behavior and understanding interfaces, API and integration points can be time-consuming and critical for developers to identify the relationships between various system components and break the functionalities.

Limited APIs & Web Services

Older legacy systems fail to access data and other functionality due to the lack of a well-defined API and web service system. The integration process is hindered by requiring constant custom development efforts, prolonging development time and increasing costs.

Data Transformation & Mapping

The data storage formats in the legacy systems have inconsistencies, errors, and structure disparity obstructing data exchange between legacy and modern systems. Before the transformation, data must be cleaned and validated for accuracy and sensitivity, increasing the time duration for integration.

Security Considerations

With legacy systems having limited to outdated authentication, issues like security breaches and unauthorized access cause potential damage to an organization’s reputation. The legacy system integration can be a high investment if security complexities persist for long.
