How to Implement a Successful Legacy Transformation

Legacy transformations, also known as legacy modernization, is the process of updating or replacing outdated software and systems. This is done to improve performance, increase security, or provide users with a more modern and user-friendly interface. In this article, we take a closer look at what exactly legacy transformations entail, how to use them and what benefits they offer.

What are Legacy Transformations?

Legacy transformations is a process of upgrading or replacing outdated software and systems with modern alternatives. This is done for a number of reasons, such as:

  • improving performance,
  • increasing security
  • replacing an end-of-life system.

The process can also be used to replace older technology with a newer, more advanced technology that better meets an organization’s current needs.

How to implement?

Deploying legacy transformations requires a thorough analysis of the organization’s current software and systems. This involves analyzing the current technologies, as well as the needs of the organization for the future. Subsequently, the alternatives are evaluated and analyzed to determine which option best suits the organization.

Once the right technology has been chosen, it is important to create a plan for its implementation. This plan contains the time schedule, resources, budgets and responsibilities. It is important to perform a risk assessment and create a plan to manage any issues that may arise during implementation.

What steps do we take in a legacy transformation?

There are several steps that can be taken to perform it successfully. Below we provide a general step-by-step plan or roadmap that can be followed:

  • Analysis of the current system landscape: We conduct a thorough analysis of the organization’s current software and systems landscape. We identify which technologies are obsolete and what needs there are for the future.
  • Evaluation of alternatives: Together we look at the different alternatives to the outdated technologies and evaluate which ones best meet the needs of the organization.
  • Plan of approach: We make a plan for the implementation of the new technology. This includes the time schedule, resources, budgets and responsibilities.
  • Risk analysis: We perform a risk analysis and create a plan to manage any issues that may arise during implementation.
  • Implementation: We introduce the new technology gradually, rather than all at once. This can help to identify and solve any problems before they become (too) big.
  • Testing: We thoroughly test the new technology before it is implemented in the production environment.
    Maintenance and management: We regularly maintain and manage the new technology to ensure it continues to work as intended.

It is important to realize that this general step-by-step plan can vary depending on the specific situation and the size of the organization.

What are the benefits of legacy transformations?

A legacy transformation can deliver a number of significant benefits. Below we discuss some of the most important:

  • Performance improvement: Replacing outdated software and systems improves performance. This leads to faster data processing, better user experience and reduced downtime.
  • Increased Security: older systems can be vulnerable to security vulnerabilities and attacks. Replacing these with modern alternatives improves security through the use of modern security measures and technologies.
  • Cost efficiency: older systems can be expensive to maintain and often difficult to adapt to changing requirements. Replacing these with modern alternatives often improves cost efficiency.
  • Flexibility: modern technologies often offer more flexibility and adaptability than older systems. This leads to greater efficiency and better adaptation to changing requirements.
  • Improving the user experience: Modern technologies often offer a better user experience and a more modern and user-friendly interface. This leads to greater user satisfaction and efficiency faster.

Cost benefits legacy transformation

From a cost perspective, legacy transformation comes at a cost in the short term. In the long run, it often leads to savings through improved performance, reduced downtime, reduced maintenance costs, and reduced security costs. The investment will be earned back in this way.

Delaying legacy transformation can lead to greater long-term risks and costs. Older systems are more prone to security vulnerabilities and attacks, and can be expensive to maintain and adapt to changing requirements. By addressing these problems in time, you may reduce costs even further.


So we can conclude that deploying legacy transformations brings many benefits, including improved performance, increased security, cost-efficiency, flexibility, and enhanced user experience.
