A customer from the aviation industry had been operating SAP BW 7.5 on HANA for over 8 years with approximately 5 TB of data volume and more than 1,200 active objects (InfoProviders, DTPs, process chains). The objective was to migrate to SAP BW/4HANA to improve performance, simplify data models, and ensure long-term maintainability.

• Upgrade to SAP BW/4HANA 2023 release
• Reduction of loading times by at least 30%
• System cleanup with more than 25% fewer objects through consolidation
• Minimal downtime: in-place migration during ongoing operations

• Execution of in-place conversion using SAP conversion tools
• Migration and adaptation of 1,050 objects (InfoCubes, DSOs, ADSOs)
• Conversion of 18 process chains to BW/4HANA-compatible variants
• Implementation of 15 new CDS views for real-time reporting

• Archiving of 1.2 TB of historical data (older than 10 years)
• Consolidation of 120 redundant data flows into 80 optimized flows
• Knowledge Transfer and Project Management
• 5 workshops with 30 key users, documentation, and handover of a migration runbook
• Project duration: 14 weeks, go-live over a weekend without unplanned downtime
• Zero data loss confirmed through post-migration checks

• 37% reduction in loading times in key process chains
• Simplified model landscape with 28% fewer objects
• Business continuity: migration during ongoing operations without impacting reporting processes
• Future-proof platform for predictive analytics and SAP Datasphere integration
