Performance tuning

6. The application development process for AS400 (IBM i) systems
involves several key steps and programming languages
Assessing the current state of AS400 systems by analyzing the
existing legacy system, identifying challenges, and defining goals
1.
Selecting a modernization approach, such as retaining
components, rehosting, replatforming, refactoring, rearchitecting,
rebuilding, or replacing
2.
Collaborating with an experienced modernization partner to
leverage the right skills and resources
3.
Iteratively testing and optimizing the modernized application to
ensure no issues with databases or connectivity
4.
Upgrading existing applications by adopting DevOps, modernizing
programming languages, databases, and user interfaces
5.
Leveraging tools like LANSA's aXes to convert 5250 green screens
to modern web interfaces without changing source code
