7 Important Steps on Your Legacy Application Modernization Journey

In today’s rapidly evolving digital landscape, modernizing legacy applications is no longer an option but a necessity. Legacy systems can hold back innovation and efficiency due to their inflexibility, high operating costs, and compatibility issues. This post will guide you through the steps to begin your modernization journey.

Steps to legacy application modernization

Step 1: Understand your current systems

The first step towards modernization is gaining a comprehensive understanding of your current application. Analyze its strengths, weaknesses, dependencies, and intricacies. This knowledge forms the foundation for deciding which parts of the system need modernization and which ones can be kept as they are.

During this consideration, think about custom developed applications as well as COTS (Commercial Off the Shelf Software). In addition, think about those customizations to COTS systems as well.

Step 2: Define the vision

Before jumping into the modernization process, define what you want to achieve. Envision what it may look like when it’s complete. Talk to stakeholders and ensure your visions are aligned. Having clear objectives will guide your modernization strategy and help measure its success.

Some of the reasons our clients proceed with modernization are:

  • Reducing technical debt
  • Improving system performance
  • Giving clients or staff a better user experience
  • Reducing operating costs
  • Improving process efficiency

All of these will ultimately lead to more profitable business!

Step 3: Choose the right modernization strategy

There are several approaches to modernization – from complete application rewrites to containerization or cloud migration. The right choice depends on your goals, budget, and time constraints. We think of modernization in three stages. How far you go on your journey should match your vision.

Extend or enhanced your UI

Enhance user experience and enable tailored processes by constructing novel front ends for existing systems. This will support improved functionality while ensuring a customized and user-friendly interface.

Refactor modern apps with your systems

By decoupling and refactoring applications, you can create a modular and composable architecture that enables easy adaptation and leverages the full potential of cloud models. This approach improves the quality of code, enhances scalability, and fosters better utilization of resources.

Rebuild your system(s)

Develop the systems you’ve always desired by seamlessly integrating them with the latest AI technologies. Avoid the substantial capital expenditures and time-consuming rebuild process that usually accompanies it, all while breaking free from the constraints of Commercial Off-The-Shelf solutions.

Step 4: Secure the Legacy Team

Embarking on the path of modernizing a legacy system necessitates a diverse blend of traditional and contemporary competencies. This is primarily because the task at hand is multi-faceted, requiring both an understanding of the past and a vision for the future.

Legacy Application

You’ll need team members who have a deep, intimate knowledge of the legacy system in question. These individuals are crucial as they understand the nuances and intricacies of the existing system. They can provide insights into why certain decisions were made in the original design, explain the system’s unique quirks, and identify potential pitfalls or challenges that might arise during the modernization process. In essence, they serve as valuable bridges between the past and the future, ensuring that important historical knowledge doesn’t get lost in the transition.

If these experts are long gone from your organization, look into contract employees or find a company to partner with that does.

Step 5: Build or Hire Modern Team

Just like you need people who are experts at the legacy system, you also need team members who are experts in new technologies. They know all about the latest things happening in technology and how to use new tools and methodologies such as low code platforms and artificial intelligence. Their job is to bring new ideas to the project and use the latest technology to make the system work more efficiently and present a better user experience.

However, the task of modernizing a legacy system can be complex and daunting. It requires not only technical expertise but also experience in managing the process, mitigating risks, and ensuring a smooth transition. That’s why it might be beneficial to consider partnering with a company that specializes in application modernization. Such companies have a proven track record in handling similar projects, and they can provide guidance, support, and expert resources to ensure your modernization project is a success.

This collaborative approach, combining historical understanding with forward-thinking innovation, is what makes legacy system modernization a truly transformative process.

Step 6: Prioritize Security

Secure applications

Legacy application modernization provides an excellent opportunity to enhance its security features. Make sure to incorporate secure coding practices and invest in up-to-date security tools. Consider all aspects of security, from data protection to access control and compliance.

At risk of sounding like a low code commercial, low code platforms are engineered to speed up the creation of safe applications. Even the best developers can’t keep up with the latest security standards. Even when building secure code today, that same code may not be secure in the future.  Platforms that generate new code on each compile are much better at solving this problem.

Step 7: Plan for Continuous Improvement

Modernization is not a one-time event but an ongoing process of improvement. Implement monitoring tools to track the performance of your modernized application. Use this data to continually refine and optimize the application.

Legacy Application Modernization is not a one-time event

The technology landscape is constantly changing, so it is important to keep your applications up to date with the latest technologies. This means regularly assessing your applications for areas that can be modernized, and then implementing those changes.

Implement monitoring tools to track performance

Once you have modernized your applications, it is important to track their performance to ensure they are meeting your expectations. Monitoring tools can help you track application response times, error rates, resource utilization, and more.

Continually refine and optimize

 The data you collect from monitoring your applications can be used to identify areas where the application can be improved. For example, if you see that the application is responding slowly, you can investigate the cause of the slowdown and implement changes to improve performance.

Final thoughts

Modernizing a legacy application can seem daunting, but with careful planning, the right team, and a strategic approach, it can lead to increased efficiency, reduced costs, and better product quality. Remember, the goal of modernization is not just to update outdated technology, but to make your application more responsive to business needs and customer demands.  This will likely also lead to higher profits.

By following these steps, you’ll be well on your way to bringing your legacy applications up to speed with the demands of today’s tech-driven world. Remember, the journey of modernization is a marathon, not a sprint. Patience, persistence, and continuous improvement are keys to success.
