Modernizing legacy systems gets tougher the faster technology advances, and our modern times are no exception. With a shrinking pool of programmers skilled in older languages like COBOL, RPG, DDS, and CL, we have a new dimension to that problem.
In part 1 of this article, we took a brief look at the history of IBM i on its 35th birthday, its continued relevance today, and its viability into the future. In this article, we discuss the need to modernize these systems to remain competitive.
We’ll also delve into the rise of programming languages like JavaScript, the impact of retiring COBOL and RPG programmers, and the role of code analysis programs in migrating from legacy systems.
Defining Legacy Systems and Their Importance
Many companies continue to use legacy applications on IBM i systems, primarily because they still serve a purpose or because replacing them would be too costly or risky. These systems often run mission-critical applications that are crucial to a company’s operations.
For many companies, these applications run on COBOL and RPG and have done so for several decades. Despite being developed in the late 1950s and early 1960s, they continue to be used in industries like banking, insurance, and government sectors.
The Shrinking Pool of COBOL and RPG Programmers
The shrinking pool of programmers skilled in these older languages is an issue that will become more severe over time, leading to higher costs, longer development times, and potential security risks. Ignoring the issue can become catastrophic.
Security and Upgrades Suffer
Security may become the most problematic over time. Security risks can only grow as more of these engineers retire, a vulnerability that just might be the most costly of all due to the lack of skilled professionals who can keep these systems secure.
A lack of the resources needed to keep upgrades current can exacerbate the security problem as well, in addition to missing out on new features that help businesses improve their agility, streamline processes, and take advantage of new technologies.
Code Analysis Programs: Aiding Migration from Legacy Systems
One solution for businesses looking to migrate from legacy systems is the use of code analysis programs like CM evolveIT. CM evolveIT can analyze your existing code, identify potential issues, and reveal a path for migrating to newer programming languages. By leveraging code analysis programs like CM evolveIT, you can efficiently and effectively transition from your legacy systems while minimizing disruption to their operations.
Success Stories: Embracing Newer Languages and Reaping the Benefits
Several organizations have successfully migrated from legacy systems to modern programming languages, reaping numerous benefits in the process. For example, a large financial institution recently migrated its core banking system from COBOL to Java, resulting in improved performance, enhanced security, and reduced maintenance costs.
Another success story involves a government agency that transitioned from an RPG-based system to a modern, web-based application using JavaScript and other modern technologies. This migration not only improved the agency’s efficiency but also allowed them to better serve their constituents.
Conclusion
In today’s rapidly evolving technology landscape, modernizing legacy systems is essential for businesses to stay competitive, reduce costs, and mitigate security risks. By embracing programming languages like JavaScript and leveraging code analysis programs, organizations can successfully migrate from legacy systems and unlock the full potential of modern technologies.
