Re-engineering Legacy Apps is Smarter (and Cheaper) Than Starting from Scratch
Table of Contents
Are you running legacy software that’s still working fine but feels outdated?
It’s a common dilemma many businesses face: Should you continue using your old system, or is it time for a fresh rebuild?
With the growing pressure to improve performance and customer satisfaction, many companies are opting for re-engineering their legacy apps. According to a recent survey, 67% of businesses in 2024 have chosen to re-engineer their legacy systems, and for good reason! Re-engineering can save you money, reduce risks, and speed up your time-to-market—without the hassle of starting from scratch.
The idea of rebuilding software from the ground up may seem tempting, but have you considered the cost, time, and potential risks involved?
This blog will dive into why application re-engineering is not just smarter but also cheaper. You’ll also learn how CodeSuite can help modernize your legacy software, boosting its efficiency and extending its lifecycle.
Why Legacy Apps Are Still Valuable
Legacy Systems
Legacy software is often the backbone of businesses. Even though it’s older, it still contains valuable data, proven functionality, and features that have been fine-tuned over time. These systems are deeply integrated into your organization’s daily operations. They’ve been optimized through years of use, so changing them isn’t always a simple decision. However, the challenge lies in balancing the need for modern features with the realities of legacy systems that can sometimes be hard to manage.
The Hidden Cost of Starting Over
Rebuilding a legacy system from scratch can be extremely costly. Depending on the complexity, it could cost anywhere between $500K to $5M. But the expense doesn’t stop there. It could take 12 to 18 months or even longer to develop a brand new application, all while your business runs the risk of downtime and disruptions. Additionally, there’s the complexity of migrating your data, retraining your team, and adjusting your processes to a new system.
On the other hand, re-engineering your existing system can save 30–40% in costs. By preserving the core structure of your current system, you can update and enhance its functionality without losing the benefits you already have. It’s a win-win for both your budget and timeline.
Benefits of Re-Engineering Your Legacy Apps
Cost Efficiency
The most immediate benefit of re-engineering is cost savings. A complete rebuild from scratch can be an enormous expense, while re-engineering leverages your existing infrastructure. This can lead to savings of up to 60%, with companies seeing significant reductions in their development costs when they choose to modernize their apps instead of rebuilding from zero.
Faster Time-to-Market
Re-engineering isn’t just cheaper; it’s also faster. By working with an existing codebase, you’re not starting from square one. Instead, you’re focusing on improving specific features and fixing problems, which accelerates the development process. At CodeSuite, we employ agile methodologies and modern tools to reduce development time by up to 40%. This means you can bring your updated app to market much faster, ensuring your business stays competitive in a rapidly changing market.
Reduced Risk
Starting from scratch carries inherent risks. Developing a new system can result in unexpected complications or delays, which can disrupt your business. Re-engineering helps mitigate those risks by retaining the core functionality of your existing system. This makes for a smoother transition and allows for a more controlled, gradual evolution of your software.
How Re-Engineering Legacy Apps Works: A Simple Process
Step 1: Assessing the Existing System
At CodeSuite, we begin by evaluating your current system. We look at everything—the code, performance, security risks, and user experience. This step ensures that we understand exactly what’s working and what’s not, so we can prioritize improvements.
Step 2: Modernizing the Tech Stack
One of the most important parts of re-engineering is modernizing your tech stack. We’ll move your app to cloud-based infrastructure, introduce APIs, and break it into smaller, more manageable parts through microservices. By integrating modern technologies like AI, machine learning, and automation, your app will be more scalable and capable than ever before.
Step 3: Improving the User Experience
A good user experience is key to customer satisfaction. We’ll give your app’s UI/UX a facelift, making it easier to use and more visually appealing. For instance, one of our clients saw a 25% increase in customer satisfaction after a simple UI upgrade.
Step 4: Execution and Testing
Once everything is set up, we implement the changes gradually, with constant testing to ensure everything is working as it should. Re-engineering doesn’t have to mean chaos—with careful planning and execution, your app will transition smoothly.
Common Myths About Re-Engineering
Myth #1: Re-Engineering Takes Too Long
Some might think that re-engineering will take just as long as building a new app. Not true! Thanks to agile methodologies, re-engineering is often quicker than starting from scratch. In fact, where rebuilding might take 12-18 months, re-engineering can take just 6-9 months.
Myth #2: Legacy Systems Can’t Be Modernized
A common misconception is that legacy systems can’t be brought up to date. But in reality, almost any legacy app can be modernized. Even more than 10-year-old systems can be transformed with the latest technologies. For example, CodeSuite re-engineered a 12-year-old legacy system, adding new features and reducing costs by 30%.
Myth #3: Re-Engineering Is Just a Quick Fix
Re-engineering is not a temporary solution. It’s a long-term strategy that keeps your app running smoothly for years to come. By continuously improving and updating your system, you ensure that it stays competitive and future-proof.
Cost Comparison: Re-Engineering vs. Starting from Scratch
Initial Costs
Let’s break it down.
Starting from scratch could cost anywhere from $500K to $5M, depending on the complexity. On the other hand, re-engineering typically costs 30–40% less. This means re-engineering your legacy system can save you hundreds of thousands of dollars—and that’s just the beginning.
Long-Term Benefits
Re-engineering gives you a quicker ROI by reducing operational costs, shortening development cycles, and cutting down on maintenance fees. The long-term savings are significant, making it a more cost-effective choice in the long run.
