Legacy Rewrites
As business processes outgrow their capabilities, legacy systems tend to break down, leading to numerous bugs and workarounds. Outdated interfaces also make them unpleasant to work with.
Why Rewrite Legacy Systems?
Outgrown Software
Business processes evolve, and legacy systems may no longer meet the organization’s growing needs. Rewriting allows you to align your software with current requirements and future goals.
Degradation and Bugs
Over time, legacy systems deteriorate, resulting in a multitude of bugs and workarounds. Rewriting enables you to eliminate these issues and create a stable and reliable software foundation.
Outdated Interface
Legacy systems often have outdated interfaces that hinder user productivity and satisfaction. By rewriting, you can design an intuitive and visually appealing user experience, enhancing user engagement and efficiency.
Legacy system rewrites are challenging projects, but with careful planning and execution, it is possible to transform them into clean, efficient, and user-friendly systems.
The Right Approach
Determine End-Game Needs
Before embarking on the rewriting process, it is crucial to clearly define your desired outcomes. Assess your business requirements and set specific goals to guide the transformation process.
Investigate Current System Construction
Gain a comprehensive understanding of the existing system's architecture and construction. Identify areas that need updating and evaluate the feasibility of making necessary modifications.
break it down
Rather than attempting a wholesale rewrite, it is advisable to break the process into manageable pieces. Prioritize components based on factors such as risk, ease of conversion, and business impact. This approach allows for a more focused and iterative modernization process.
Technical Isolation
Isolate the code responsible for each component you plan to rewrite in the legacy system. Develop test harnesses to capture the behavior of the existing code without making any changes. This monitoring approach ensures a clear understanding of the system's current functionality.
Develop Modern Services
Create new, modern services to replace the outdated functionality in the legacy system. By leveraging contemporary technologies and best practices, you can design efficient and scalable solutions that meet your current business needs.
replace and test
Gradually replace each isolated component in the legacy system with the new, modern counterpart. Continuously monitor and test the system to ensure proper functionality. Rinse and repeat this process until the entire system is transformed.
The Challenges of Legacy System Rewrites
Rewriting legacy systems is one of the most complex projects you can undertake. Unlike starting from scratch, transforming a 20-year-old system requires surgical precision to avoid disrupting existing functionality.
Legacy systems were often built using outdated practices and may not be conducive to easy rewriting. However, with the right approach, it is possible to overcome these challenges and create a modern system.
Transition and Adoption
Transitioning from a legacy system to a modern one requires careful planning and employee adoption. While we provide support in terms of training and transition plans, it is essential for your organization to embrace the change.
Training and Support
We offer comprehensive training programs to ensure your staff is equipped with the necessary skills to work with the new system. We provide ongoing support during the transition phase to address any questions or concerns.
Overcoming Resistance
Sometimes, transitioning from outdated practices to modern systems can be challenging. For example, if legacy reporting has been compromised by integrity issues, users may initially distrust the new system’s high-integrity data. We help you address these concerns and facilitate a smooth transition.
Organization-Wide Process
Adopting a new system is not just an IT initiative—it is a holistic, organization-wide task.
