In today’s business world, the ability to innovate and adapt quickly to technological changes is crucial to a company’s success and survival in the marketplace.

In this sense, one of the main challenges faced by organizations is dealing with legacy software systems, which can limit business growth, efficiency, and security.

Therefore, we will explore the importance of modernizing legacy software and the key steps in order to do so as safely and efficiently as possible. Keep reading until the end!

Why modernize legacy software?

Unfortunately, there is no single answer to this question, since the reasons for modernizing legacy software may be the result of the company’s momentum, or even an adaptation to government laws, for example.

That said, we have gathered the 7 main points where this is common, which you will be able to check below:

1. Improved performance and efficiency: Legacy software may have difficulty coping with the increasing demands of processing and scalability. Modernization allows you to optimize system performance, improving processing speed, responsiveness and operational efficiency;
2. Improved information security: Legacy systems may be more vulnerable to cyberattacks and security breaches due to the obsolescence of the technologies used. Modernization helps mitigate these risks by protecting the organization’s data and infrastructure;
3. Facilitating integration: Legacy software can be incompatible with new technologies and platforms, making it difficult to integrate with other systems and adopt new solutions. Modernization allows for greater interoperability and flexibility, making it possible to connect with other applications and services to expand their potential;
4. Cost reduction: Maintaining legacy systems can be expensive, especially when considering the cost of maintenance, support, and the need for specific solutions for compatibility. There is also the high cost of employing the professional specialized in a particular technology, often obsolete. In this sense, modernization can help reduce these costs in the long run, as well as increasing efficiency and productivity;
5. Increased competitiveness: companies that invest in the modernization of their legacy software are better prepared to face competition and adapt to market changes. Modernization allows you to take advantage of technological innovations and offer higher quality products and services to customers;
6. Improved user experience: Legacy software may offer a limited user experience. Modernization can improve usability, interface and accessibility, providing a more pleasant and efficient experience to users;
7. Regulatory compliance: In some cases, regulations and industry standards require companies to update their legacy systems in order to ensure compliance. The evolution ensures that the organization is up to date with these requirements to avoid possible penalties in fines for misalignment with good business and legal practices.

As previously mentioned, these are the main, but not the only, reasons to consider modernizing legacy software. And now that you understand what these points entail, let us get to know the steps required to make this possible.

Key Steps in Legacy Software Modernization

Legacy software modernization is a complex process and can vary depending on the specific needs and goals of each organization. Therefore, some of the steps that we will show below may not make sense in some businesses contexts, and should be adapted accordingly. 

Overall, these are the most common steps in modernization projects:

• Initial evaluation;
• Definition of the strategy;
• Planning and prioritization;
• Development;
• Tests;
• Migration;
• Monitoring and maintenance.

Initial assessment

The first step is always to evaluate the legacy software and identify its strengths and weaknesses. This includes analyzing the performance, security, scalability, and compatibility of the current system. At this stage, it is crucial to understand business requirements, user expectations, and long-term goals.

Strategy definition

On the basis of the assessment, the most appropriate modernization strategy needs to be defined. Common approaches include reengineering, re-platforming, re-architecting, and encapsulation. The choice of strategy will depend on the specific needs of the organization, the resources available, and the constraints in terms of timeframe and budget.

Planning and prioritization

After selecting the modernization strategy, it is necessary to draw up a detailed plan that includes clear objectives, deadlines, required resources, and cost estimates. At this stage, it is important to prioritize the system components that need to be modernized first, considering the business impact, complexity, and associated risks.

Development

The development phase involves executing the modernization plan, applying the necessary changes to the legacy software. This can include refactoring code, migrating to a new platform, restructuring the architecture, or integrating with APIs and services.

During implementation, it is crucial to follow software development best practices and ensure code quality.

Tests

Before implementing modernized software into production, it is essential to conduct rigorous testing in order to ensure that the system works as expected and is free of errors and vulnerabilities. This includes testing usability, functionality, performance, security, and compatibility.

Migration

At this stage, the modernized software is put into production, either by replacing it or having it coexist with the legacy system. It is important to ensure a smooth transition and minimize the impact on users and business processes.

In this sense, it may be necessary to create a data migration plan, training users, and providing support during the change process.

Monitoring and maintenance

After the modernized software is deployed, it is critical to monitor system performance, security, and availability on an ongoing basis. This allows you to quickly identify and fix problems, as well as ensure that the software stays up-to-date and compliant with industry standards and regulations.
