Code rewrite presents itself as a solution to diverse situations that could become an issue regarding software development.
But, first and foremost, what is code rewrite? Code rewrite refers to the process of modifying or refactoring an existing codebase to improve its structure, readability, performance, or maintainability without changing its core functionality.
This can involve several activities, such as refactoring, optimization, bug fixing, correcting errors and issues that were present in the original code, updating libraries and dependencies and code modernization.
Understand code rewriting and its importance through this article, where you will find everything you need to know about it and how to maximize its benefits.
The Importance of Code Rewrite
Before delving into code rewrite subtleties, it is essential to understand the importance of code rewrite. Code rewrite is an essential tool nowadays that has the potential to bring significant improvements and benefits to a software project.
Not only due to maintainability but also to improve performance, code rewrite allows you to improve your day-to-day work in software development companies,
Code rewrite is also key for scalability, technical debt reduction and security, among others. While often resource-intensive, it can provide substantial long-term benefits, ensuring the software remains robust, maintainable, and capable of meeting current and future needs.
But why should you consider code rewrite? As has been implied before, code rewrite can be beneficial for several reasons, which you will find listed below. Its functionalities also carry key benefits that can become game changers in software development.
Over time, code can become cluttered and difficult to maintain. Code rewrite improves code quality so that a rewrite can clean up the codebase, making it more readable and maintainable.
Moreover, as legacy code might not be optimized for modern hardware or software environments, rewriting the code can improve its performance, making it faster and more efficient.
When we think about debt, economic issues are what come up first. However, technical debt can become a huge matter as accumulated technical debt can slow down development and introduce bugs. A rewrite helps in addressing these issues, leading to a more robust and reliable codebase.
On the other hand, software development practices evolve, and newer paradigms and technologies can offer significant benefits. Rewriting the code allows incorporating these modern practices, such as better design patterns, new language features, or updated frameworks.
Another relevant matter is security. Older codes might have security vulnerabilities that weren't known or addressed at the time it was written. A rewrite can help to identify and fix these issues, making the application more secure.
Modernization is also key regarding any kind of technological issue and software development isn’t the exception. Sometimes, adding new features to an existing codebase is more complex and error-prone than rewriting the code. A fresh codebase can be designed with future enhancements in mind, making it easier to extend.
What’s more, modernizing the codebase can help in integrating with new systems, APIs, or services that weren't available or considered during the initial development.
Last but not least, clean, well-organized code improves developers' productivity, making it easier to onboard new team members and reducing the time required to understand and modify the code.
Although the long-term benefits often outweigh the initial costs, especially if the existing codebase is significantly hampering productivity, performance, or security, code rewriting can be risky. But don’t panic; we’ve got you. Dive into the following section to further understand how to rewrite code in the safest way possible.

Factors to Consider Before Rewriting Code
Assessing whether to undertake a code rewrite involves evaluating several factors to determine if the benefits outweigh the costs and risks.
Firstly, it is crucial to understand the current code quality you are working with. This means evaluating its readability, maintainability, and technical debt.
Additionally, analyzing performance issues and security concerns is fundamental to assessing code rewrite.
Regarding work itself, development and maintenance costs are one of the main reasons to evaluate code rewrite due to two main reasons: if bugs occur frequently or the current code is slowing down, work can become extremely uncomfortable, leading not only to further issues but also to demotivation.
Technology is constantly moving forward. Introducing modern practices could require a codebase that can support it to improve productivity. This could be helpful regarding future requirements.
Taking into account resource availability such as enough skills and knowledge for a rewrite is essential. However, if not, Jalasoft has a huge background when it comes to code rewrite. Hiring an external team for code rewrite can also be advantageous concerning time and human resources as it can also diminish risks of failure.
Follow the following steps to assess the need for a code rewrite:
Conduct a thorough review of the existing codebase to identify issues and areas for improvement.
Analyze current performance and identify any critical issues.
Gather input from developers, users, and other stakeholders on current pain points and desired improvements.
Estimate the costs and benefits of a rewrite.
Prototype and experiment to evaluate feasibility and potential benefits.
Develop a plan to mitigate risks, such as incremental rewrites, thorough testing, and maintaining the old code as a fallback.
Choosing the Right Code Rewrite Approach
After taking into consideration each step needed to assess if code rewrite is necessary (or maybe even good for your company), it is crucial to understand the difference between refactoring and rewriting. Below are two charts: one that compares refactoring with rewriting and another that helps you understand when to refactor and when to rewrite.

Best Practices for Code Rewrite by Jalasoft
After conducting a thorough analysis of your code performance, if you identify some or several of the issues we have mentioned above, such as the need to improve code quality or performance optimization, maybe it's time for a code rewrite.
However, comfort, as we have stated before, isn’t the only reason for code rewriting. Identifying if security enhancement is needed to cover yourself from any future problems or even focusing on reducing technical debt can be key for code rewriting.
Modernization is also fundamental when evaluating code rewrite. Adopting modern technologies to improve scalability and, as a consequence, facilitate future development is key for any business to thrive.
Nonetheless, one crucial step before diving into code rewrite is collaboration with stakeholders.
First and foremost, identifying stakeholders is key to determine who will be impacted by the rewrite, such as developers, project managers, product owners, end-users, and other relevant parties.
Moving on, together, you should define objectives and ensure alignment on goals such as improved performance, security, scalability, and maintainability.
Communication is key in this step. Stakeholders should be kept informed about the rewrite process, timelines, and expected outcomes.
To ensure the process is clean, you may provide comprehensive documentation and training sessions to help stakeholders understand the new codebase. This is especially important for developers and maintainers.
Moreover, collaborating on identifying potential risks and developing mitigation strategies could also be a game changer. Stakeholders can offer valuable insights into potential issues and solutions.
Finally, implementing testing and QA processes is what defines success in code rewrite.
While testing is a visualizable way to understand if your prototype is applicable and effective QA (Quality Assurance) testing could require an expert's eye. Fortunately, at Jalasoft we have years of experience and results to help you out.
But first, let’s understand the impact of testing and QA Processes.
