The top 5 benefits of Legacy System Modernization: Transforming for a better digital future

Over time, enterprise level businesses face many challenges in supporting their legacy applications. These applications are essential for the running of the business, yet the maintenance costs and support requirements that they present mean an over-inflation of costs that have a drastic effect on their bottom line.

Reengineering is the systematic transformation of an existing system into a new form to realize quality improvements in operation, system capability, functionality, performance, or evolvability at a lower cost, schedule, or risk to the customer

Refactoring and reengineering are essential to software evolution and maintenance. Their main goal is to ensure software is maintainable and useful throughout its lifetime. And while code refactoring seems like something only developers can make use of, it’s ultimately a business decision. Here are five business benefits of refactoring and reverse engineering.

  1. Increased productivity: The performance of a software is generally measured by its speed and accuracy. Optimizing the code and database through reengineering helps the software to run faster and perform better than its legacy version.
  2. Reduced risk: Reengineering is based on incremental improvement of systems, rather than radical system replacement. The risk of losing critical business knowledge, which may be embedded in a legacy system, or of producing a system that does not meet its users’ real needs, is drastically reduced.
  3. Saves times and resources: Instead of starting the development from scratch, the existing solution is simply transferred to a new platform, harnessing the existing business logic and transforming it using a structured approach saving time and resources.
  4. Cost Effective: Although some may argue, but software reengineering is a cost-effective method for software development. This process allows you to discover unnecessary steps and resources that have been implemented in your legacy software and remove them from the re-engineered implementation, therefore minimizing the costs (time, financial, direct, indirect, etc.) in the long run.
  5. Ease of maintenance: In relation to cost savings, this process also makes your products easier to maintain. Being able to re-inspect your software leads you to point out several missteps in the existing implementation allowing you to decide on changes in the reengineered solution. This, therefore, makes the maintenance of your new solution much easier to execute and sustain.


Reengineering the legacy applications to harness the newest technologies and environments is crucial in ensuring the ongoing success of your business. With growing competition and introduction of modern technologies, it is necessary that the applications stay up-to-date and should be maintainable, reusable and extensibility-friendly to satisfy customers and beat competitors. Aress Software has been instrumental in application reengineering and upgrading to modern platforms using proven processes, expertise and technologies along with offering a more flexible way to respond to changes in your market while providing the benefit of robust technical support.
