Why existing IT staff remain essential during legacy application modernization
April 9, 2025 4 minutes
The world of IT is changing at lightning speed. Legacy applications, often built with outdated technologies, frequently pose a bottleneck to growth and innovation. Many organizations are therefore opting for modernization – and understandably so. A common concern among IT professionals is that their specialized knowledge of legacy systems will become obsolete. This leads to uncertainty about their future within the organization. However, this fear is unfounded, as the modernization of legacy applications actually presents new opportunities for IT professionals to grow and develop.
In practice, we see many IT professionals who have built up years of knowledge and experience in developing, maintaining, and supporting legacy systems. These employees are of immense value to the company, as they ensure that critical business processes continue to run on legacy software. Rather than fearing for their jobs, these IT professionals should embrace modernization and seize the opportunities for personal growth and more challenging responsibilities. Moreover, their in-depth knowledge and experience with legacy systems make them key players in the application modernization process.
Indispensable role during the modernization process
In-depth knowledge of existing systems is invaluable during the modernization process. Existing IT staff understand the business logic, data structures, and processes tied to the legacy applications. This knowledge is critical to ensure a successful migration to modern technologies. Experienced IT professionals essentially serve as the bridge between the old and the new. This unique position makes them indispensable to the success of the project. Their expertise is essential for accurately translating complex business rules to new platforms, guiding and validating data migration, and verifying the functionality of the modernized applications.
Opportunity to grow as an IT professional
The modernization of legacy applications also provides IT staff with the opportunity to expand their skills. This means that existing IT professionals will learn new technologies, apply problem-solving skills in a modern context, and increase their value to the organization through their unique combination of legacy knowledge and new skills.
As part of the modernization process, many organizations invest in training and education for their IT staff. This often includes training in modern programming languages and frameworks, cloud technologies, microservices architectures, DevOps, and Continuous Integration/Continuous Delivery (CI/CD). An IT professional who undertakes these training programs increases their value to the organization and simultaneously strengthens their position in the job market.
Existing IT professionals need to realize that the modernization of legacy applications does not mark the end but rather a new beginning in their careers. The application of new technologies creates a work environment where IT specialists can further develop their talents and skills.
More challenging tasks and a better work-life balance
Legacy applications are generally difficult to maintain, vulnerable to security breaches, and can present scalability challenges. A lot of time and energy is spent keeping legacy applications operational. Modern applications, on the other hand, tend to function more stably, offer greater opportunities for automation and innovation, and require less manual maintenance. This means that after the implementation of a modern application, an IT professional can focus more on strategic and challenging tasks, rather than spending time maintaining outdated systems. It also leads to a better work-life balance, as unexpected (night-time) interventions outside of working hours with failing legacy applications will occur much less frequently.
The future for IT specialists is promising
The modernization of legacy applications should certainly not be seen as a threat to the careers of existing IT professionals. On the contrary, it is an opportunity for them to grow as experts. They are given the chance to acquire new knowledge and experiences and take on more challenging tasks. In combination with their existing knowledge of the organization, legacy applications, and internal processes, they become invaluable assets to the company.
