Below is First Option's approach to Application development.
Should you re-write your existing IBM i (iSeries) application using a language other than RPG OR move to a different software solution?
As technology becomes more advanced and modifications are needed to move the company forward, integrating additional functionality into these legacy applications requires resources with experience in the old and new technologies. As the original OS or hardware legacy application was developed on (such as IBM iSeries in our example) has newer versions, leveraging the new data base and programming features of the new version of the OS is extremely important. The problem is finding a team that can integrate the new modifications into the existing IBM i (iSeries) application.
In most cases these ‘legacy’ applications are feature rich with complex business rules. A total re-write could be an investment measured in years and millions of dollars. The expense does not end with the IT cost but continues with the disruption of your organization in terms of training and may include new processes and procedures influenced by the technology shift instead of your business needs.
