In this blog article, we will delve into the key strategies for successfully modernizing legacy applications, including identifying business goals, assessing the current state of the application, choosing the right approach, and maintaining and updating the modernized application. By the end of this article, you will have a solid understanding of the benefits and considerations of application modernization, and be equipped to begin modernizing your own legacy applications.

Identify the business goals of modernization

One of the first steps in the application modernization process is to identify the business goals that will drive the project. This will help ensure that the modernization effort is aligned with the overall strategy and objectives of the organization.

There are several common business goals that can be achieved through application modernization:

  1. Cost reduction: Modernizing legacy applications can help reduce maintenance and operational costs by streamlining processes, eliminating the need for custom workarounds, and reducing the number of applications and systems in use.
  2. Improved efficiency: Updating outdated applications can improve efficiency by providing more automation, better integration with other systems, and a more intuitive user experience.
  3. Improved customer experience: Modernizing legacy applications can help improve the customer experience by providing more reliable and responsive systems, as well as new features and functionality that are in line with current market demands.
  4. Increased revenue: Modernizing legacy applications can also help drive revenue growth by enabling new business models, such as offering new products or services or entering new markets.

By clearly defining the business goals that will drive the modernization effort, organizations can ensure that the project is focused on delivering the maximum value and benefit to the business.

Assess the current state of the legacy application

Before embarking on a modernization project, it’s important to thoroughly assess the current state of the legacy application. This will help organizations understand the scope and complexity of the project, as well as identify any potential challenges or obstacles that may need to be addressed.

Here are some key areas to consider when assessing the current state of the legacy application:

  1. Technology stack: What technology and programming languages are used in the current application? Is the technology still supported and maintained by vendors? Are there newer technologies that could provide benefits such as improved performance or security?
  2. Architecture: How is the application architected? Is it a monolithic application or is it composed of microservices? Understanding the architecture will help determine the level of complexity involved in modernizing the application.
  3. Data: How is data stored and accessed in the current application? Is the data structured or unstructured? Is the data consistent and accurate, or is it duplicative or outdated? Understanding the data requirements will help determine the level of effort required to migrate and integrate data into the modernized application.
  4. Dependencies: What other systems or applications does the legacy application depend on? Are these dependencies still relevant and in use, or can they be eliminated or replaced? Understanding dependencies will help organizations avoid any potential disruptions or impacts on other systems during the modernization process.

By thoroughly assessing the current state of the legacy application, organizations can gain a better understanding of the work required to modernize the application and plan accordingly.

Choose the right modernization approach

Once the business goals and current state of the legacy application have been identified, the next step is to choose the right modernization approach. There are several options to consider, each with its own set of benefits and considerations.

  1. Re-platforming: This involves moving the application to a new platform, such as a new operating system or infrastructure, without making any significant changes to the code. This can be a cost-effective way to modernize an application, but may not address deeper issues such as outdated technology or a poor user experience.
  2. Refactoring: This involves making changes to the code and architecture of the application to improve its performance and maintainability, but without changing the core functionality. This can be a good option for applications that are still relevant but are suffering from technical debt or inefficiencies.
  3. Re-engineering: This involves significantly overhauling the application to improve its functionality and user experience. This can be a more complex and costly approach but can deliver significant benefits if the legacy application is no longer meeting the needs of the business.
  4. Replacing: In some cases, it may be more cost-effective or efficient to replace the legacy application with a new, off-the-shelf solution. This can be a good option if the legacy application is very outdated or is no longer supported by the vendor.

When choosing the right modernization approach, organizations should consider the business goals, the current state of the application, and the level of complexity and cost involved. By carefully evaluating these factors, organizations can choose the approach that best meets their needs and delivers the greatest value.

Implement the modernization plan

Once the modernization approach has been selected, it’s time to implement the modernization plan. This will typically involve setting up a project team, developing a detailed plan and timeline, and testing and validating the modernized application.

  1. Set up a project team: As with any project, it’s important to assemble a team of skilled professionals who can execute the modernization plan. This may include developers, architects, project managers, and other relevant experts. It’s also important to involve stakeholders from across the organization to ensure that the modernized application meets the needs of all relevant parties.
  2. Develop a detailed plan and timeline: A clear and well-defined plan is essential to the success of the modernization project. This should include a timeline for each phase of the project, as well as specific tasks and responsibilities for each team member. The plan should also include contingencies for potential issues that may arise during the modernization process.
  3. Test and validate the modernized application: Before rolling out the modernized application to production, it’s important to thoroughly test and validate the application to ensure that it meets the desired business goals and functions as expected. This may involve conducting user acceptance testing, performance testing, and other types of testing to ensure that the application is ready for use.

By following a structured and well-planned approach, organizations can successfully implement the modernization plan and realize the full benefits of modernizing their legacy applications.

Maintain and update the modernized application

Once the modernization project is complete and the modernized application is in production, it’s important to maintain and update the application to ensure that it continues to meet the needs of the business. This may involve regularly monitoring performance and usage, implementing updates and security patches, and considering the adoption of continuous integration and delivery practices.

  1. Monitor performance and usage: Regularly monitoring the performance and usage of the modernized application can help organizations identify any issues or opportunities for improvement. This may involve collecting and analyzing metrics such as response times, error rates, and usage patterns.
  2. Implement updates and security patches: As with any application, it’s important to keep the modernized application up to date with the latest security patches and updates. This will help ensure that the application remains secure and reliable.
  3. Consider incorporating continuous integration and delivery practices: Adopting continuous integration and delivery (CI/CD) practices can help organizations quickly and efficiently deliver updates and improvements to the modernized application. By automating the build, test, and deployment processes, organizations can reduce the time and effort required to roll out updates and improvements.

By maintaining and updating the modernized application, organizations can ensure that the application continues to deliver value and meet the evolving needs of the business.


In conclusion, application modernization is a critical process for organizations looking to improve the efficiency, reliability, and relevance of their legacy applications. By identifying business goals, assessing the current state of the application, choosing the right modernization approach, and maintaining and updating the modernized application, organizations can successfully modernize their legacy applications and realize the full benefits of this process.
