The 5-Step Migration Framework: From Assessment to Execution

Successful execution of an sap bw to azure migration requires a methodology that balances technical precision with business continuity. It’s not enough to move data; you must replicate the complex intelligence built into your legacy system while optimizing it for a cloud-native future. Our framework guides enterprises through this transition, ensuring that every object, dependency, and business rule is accounted for before the first byte leaves your on-premise environment.

• Step 1: Deep-dive Assessment. Conduct a comprehensive audit of your SAP BW objects, including InfoProviders, Transformations, and Process Chains. Identifying unused or redundant data at this stage prevents the “lifting and shifting” of technical debt.
• Step 2: Sizing and Cost Modeling. Design your Azure landing zones with precision. Use current performance metrics to model your storage and compute requirements, ensuring your environment is cost-effective from day one.
• Step 3: Extraction Selection. Determine the most efficient path for data movement. Whether you utilize Azure Data Factory (ADF), Operational Data Provisioning (ODP), or specialized third-party connectors, the choice must align with your volume and latency requirements.
• Step 4: Data Validation and Reconciliation. Implement automated testing to verify that 100% of your business logic has transitioned correctly. Discrepancies in financial or operational data can undermine the entire project’s credibility.
• Step 5: Cutover and Performance Tuning. Execute a phased cutover to minimize downtime. Once live, continuously tune your Azure resources to match actual workload patterns, maximizing the ROI of your new platform.

Choosing Your Extraction Strategy

Your extraction method is the heartbeat of the migration process.
