Archiving and decommissioning of a legacy application (Host, PL/1, C) to SAP

This legacy application, which runs on the mainframe and was migrated to SAP in a previous project, maps business processes related to construction financing, mortgage management, and repayment management. The migration of legacy data for archiving purposes is carried out using batch programs and generally applicable modules, the latter covering the various thematic areas. Batch processes still running within the legacy application must be identified, deactivated, and dismantled. The implementation of requirements, regular test runs, and the planning of the decommissioning are carried out in close collaboration with the relevant department.
