From our previous blogs, you must know the history of IBM AS400 systems and their own OS/400. Today’s AS/400 is known as the IBM iSeries, and it is used not only by medium-sized organizations, but many Fortune 500 companies also use it.

AS/400 is well known for its robustness, reliability, scalability, and security. Also, the IBM AS400 iSeries can store valuable information and core business logic in large volumes. Today, however, data becomes the key driver for business intelligence, and the demand to integrate the AS400 system (Green Screen) with other technologies has arisen. Organizations are looking to modernize the IBM AS400 application and make it better and more user-friendly. Furthermore, various surveys show that users are not happy with the outdated interface. The lack of automated features is one of the fundamental reasons organizations invest and upgrade their legacy applications.

While the hardware cost may not be an issue for various organizations, as TCO will be reduced up to 35% after migration, but AS/400 migration to new OS can be a stressful experience.

Process of Migration

The process of migration consists of various tasks. Data extraction of the source system, transformation, validation, and loading of final data in the destination system. Have a look at the step-by-step process:

  1. Planning is the initial stage of migration. It includes identifying stakeholders, analyzing the source and destination, and deciding the most appropriate tools to be used.
  2. Analysis and design are the next stages in which business users perform a detailed evaluations to define the needed actions to be carried out.
  3. Implementation is the essential phase of the migration process, and it is responsible for extracting, transforming, and validating.
  4. Migration is the last phase where source files are moved to the destination, and the project is handed over to key business users.
