Database upgrade for a billing and controlling system

For the stability and IT security of the ERP system developed in-house, an upgrade from a current Oracle version is indispensable. Two versions, each based on one of the two Oracle versions, are tested and compared in the areas: Administration, accounting, controlling, financial accounting, personnel, project management, reporting. Problems caused by the conversion are eliminated either by software adaptations or changes to the Oracle parameters. In addition, the necessary adaptations of the ABS system are implemented in parallel due to technical requirements.
