Service software for migrating configuration data

The further development has made it necessary to transfer multiple initial data models to a single standard in order to use this standard to enable correct transformations of the configuration data and a corresponding export to the target systems. Altered customer requirements have expanded the original plan for a 'two systems in one' solution into a 'five systems in two' transformation solution. At the start of the project, there are no documented requirements and no test case basis. The most important tasks therefore, besides eliminating errors, are clarifying the content and documentation, as well as creating a regression test basis.
