The migration procedures are realized to such an extent that migration to the productive system can be carried out.

Different realization steps are carried out depending on the process.

The detailed specifications are developed on the basis of the migration concept. Migration quality has a major influence on the operational launch of the new system. Accordingly, quality assurance measures are of key importance.

The migration procedures are tested according to the test concept. This is done with the tests module.
