Spinning Off Company Codes

The new three-system architecture will be implemented in two phases. In the first phase, the systems will be set up as copies of the existing architecture. This phase will involve preparing for the integration of interfaces, testing basic functionalities, and performing quality assurance on the technical infrastructure. This also includes, among other things, determining the interfaces required in the target system, identifying users and stakeholders, conducting technical interface tests, and planning the go-live. After the business tests are completed, the new production system is updated as part of the cutover by copying the data from the legacy system. During the cutover, all relevant interfaces and jobs in the source system must be stopped and rescheduled in the target system. Users must be locked or unlocked depending on their tasks and their affiliation with the respective systems.
