Replatforming Legacy Code with Mendix: A Step-by-Step guide

In the dynamic landscape of technology, legacy systems often become roadblocks, disrupting workflows and posing security threats to an organization’s IT infrastructure. The solution? Replatforming legacy code.

The concept of replatforming legacy code has been widely popularized in recent times, and many developers are actively using this strategy to move an application from one platform to another without altering the functionality. However, you can only enjoy the benefits of replatforming legacy code if you choose a reliable platform like Mendix.

So, here’s a quick look at the various challenges associated with legacy systems and how these challenges can be mitigated with Mendix solutions, the ultimate tool for replatforming legacy code.

Understanding Legacy Code

A legacy code is a code that the developers are “scared to change.” It is the source code of an application that was generated a long time ago, and since then, it has been subjected to repeated modifications. These codes can be detrimental to the functioning of the application and also reduce the scope of scalability and integration. 

Problems associated with legacy code: 

  • Lack of Structure: Legacy code does not follow proper coding structures and principles. Their codes are also not documented.
  • Complexity: Present-day developers find it hard to understand legacy code. Making changes to the code also becomes a difficult affair.
  • Outdated technology: Legacy code mostly contains outdated frameworks and technologies that might not work in the current development landscape.
  • Performance bottlenecks: Legacy systems fail to achieve the desired performance, thereby impacting workflows.
  • High Technical Debt: Legacy code tends to accumulate technical debt, which increases the cost of maintaining the systems. 

The impact of legacy code on business operations and agility: 

  • Loss of business ability: Legacy systems can cause a loss of agility in business. It prevents business operations from being carried out smoothly and effectively.
  • Time lags: The developers also have to face time lags now and then, leading to business operations delays. Sometimes, there is a huge business loss.
  • Increased maintenance charges: Using legacy systems for your business operations can drastically increase the cost of maintenance.
  • Compliance issues: The application may become vulnerable to security threats, leading to compliance issues.
  • Lack of scalability: The business cannot accommodate increased demands due to lack of scalability of their legacy systems.

The Need for Replatforming

Replatforming involves transforming a legacy system into a modernized one to gain better scalability and provide users with better performance. During replatforming, part of the code is rewritten. This allows you to enhance your existing business structure and maintain a smooth workflow. Software modernization offers a greater scope of scalability. The integration capabilities are also improved.
