The ROI of Legacy System Migration: Is It Worth the Investment?

Integrating and enhancing corporate information technologies has become crucial as business firms rely on their IT systems to drive the production and delivery of services, and to execute operations in today’s dynamic market environment.

However, many organizations today continue to use legacy systems- old technologies that, despite being effective, are unable to meet today’s requirements. Migrating from these systems to more advanced solutions is a massive decision and is frequently accompanied by hesitation due to perceived costs and risks. This raises the question: is investing in information system legacy system migration services optimally?

To answer this question, let’s look at the return on investment (ROI) involved for organizations when undertaking legacy system migration and how these organizations can assess whether it is bringing them profit.

Understanding Legacy Systems

Legacy systems can be described as outdated software, hardware, or application development services that are still in use, in organizations, even when today’s advanced technology has far better solutions for them. These systems may have been useful at the time of implementation, but are no longer efficient to support modern requirements. Common challenges associated with legacy systems include:

• High Maintenance Costs

Old systems may be costly to maintain and support because vendors may have discontinued supporting them, and the acquisition of spare parts is very challenging.

• Lack of Scalability

They usually cannot contend with a rise in workload or conform to new technologies as experienced with legacy systems.

• Security Vulnerabilities

The old systems are easier to hack for this reason and do not possess the advanced security of today’s solutions.

• Reduced Efficiency

When using legacy systems, there is restricted use of automation and current characteristics of operations.

While legacy systems may continue to function, they often act as a bottleneck for innovation and growth.

What Is Legacy System Migration?

Legacy migration solutions involve transitioning from outdated systems to modern IT infrastructure, applications, or platforms.

This can take various forms, such as:

• Rehosting

Moving the legacy system to a new environment, such as a cloud platform, without changing its core functionalities.

• Refactoring

Making changes to the existing system to improve its performance or scalability while retaining its core purpose.

• Replacing

Retiring the old system entirely and implementing a new one.

Each approach has its pros and cons, and the choice depends on factors like the organization’s goals, budget, and existing technology stack.
