Your organization’s migration from SAP BW (Business Warehouse) to SAP DataSphere, formerly SAP Data Warehouse Cloud, represents a critical modernization initiative for your data infrastructure. As a cloud-based platform, SAP DataSphere enhances SAP BW operations by enabling real-time analytics, top-level scalability, and streamlined integration functions. The guide presents an actionable framework that outlines the essential procedures for performing a migration strategy from planning through execution.
1. Assessment and Planning
The migration process begins with thoroughly assessing your current SAP BW environment and defining clear migration objectives.
- Evaluate Current Landscape: Identify SAP BW components, data models, and dependencies. Document business logic and customizations to ensure they are replicated or optimized in the new system.
- Define Objectives: Organizations must decide whether to conduct an essential lift-and-shift operation or initiate a full-scale transformation using SAP DataSphere’s advanced features.
- Stakeholder Engagement: Business stakeholders and IT personnel must engage in shared requirements and priority alignment.
- Budget and Timeline: The first task is determining practical organizational boundaries while planning resource allocations and implementation schedules.
2. Data Preparation
Preparing your data ensures a clean and efficient migration.
- Data Inventory: Identify all data sources connected to SAP BW and categorize them based on relevance, usage frequency, and size.
- Data Cleanup: Remove redundant, outdated, or unused data to optimize migration.
- Data Governance: Ensure compliance with data security and privacy regulations. Define robust access controls and policies for data usage in SAP DataSphere.
3. Environment Setup
Set up the new SAP DataSphere environment to support your migration.
- Provision SAP DataSphere: Configure the cloud environment, including user roles and permissions.
- Connectivity Setup: Establish connections between SAP DataSphere and existing data sources, such as SAP HANA, SAP BW, and non-SAP systems.
4. Data Model Transformation
Transform your SAP BW data models to fit SAP DataSphere’s architecture.
- Analyze SAP BW Data Models: You should find all information cubes, data source objects, multiproviders objects, and queries in the SAP BW system.
- Recreate Models in DataSphere: SAP DataSphere’s graphical modeling tools allow you to create equivalent data models. Simplify complex structures where possible.
- Utilize Prebuilt Templates: Leverage SAP-provided templates for specific industries and functions to accelerate migration.
5. Data Migration
Migration involves extracting, transforming, and loading data into SAP DataSphere.
- ETL Process: To extract and transform data, use tools like SAP Data Intelligence, SAP BW Open Hub, or APIs. Then, load the transformed data into SAP DataSphere.
- Batch or Real-time Options: Choose between batch migration or real-time replication using tools like SAP SDI (Smart Data Integration).
6. Testing and Validation
Thorough testing ensures the integrity and functionality of the migrated data.
- Data Accuracy: Validate that the migrated data is consistent, complete, and correct.
- Functional Validation: Test data models, analytics, and reports to confirm they deliver the same or improved results.
- Performance Testing: Evaluate query performance and data processing efficiency in SAP DataSphere.
7. User Training and Change Management
Prepare your organization for the transition.
- Train Users: Provide training on SAP DataSphere’s interface and features for both business users and IT teams.
- Update Processes: Redefine workflows and data management processes to align with SAP DataSphere.
- Communication Changes: Ensure stakeholders understand the benefits and operational changes associated with the migration.
8. Go-Live and Monitoring
Launch the new system and monitor its performance.
- Phased Rollout: Start with a pilot phase before full deployment to minimize risks.
- Monitor System Performance: Use monitoring tools to track data integration, query performance, and user activity.
- Support and Feedback: Establish a support system to address issues and gather feedback for continuous improvement.
9. Decommissioning SAP BW
Once SAP DataSphere is fully operational, decommission SAP BW.
- Transition Period: Maintain SAP BW alongside SAP DataSphere until all functionalities have been validated.
- Data Archiving: Archive historical data from SAP BW that is no longer needed.
- System Shutdown: Decommission SAP BW after confirming all critical functionalities are operational in SAP DataSphere.
10. Continuous Optimization
Pattern continuous system improvement to attain lasting business success.
- Leverage Advanced Features: Examine SAP DataSphere’s functionality, including machine learning, advanced analytics, and real-time insights capabilities.
- Performance Tuning: Regular performance evaluations of data models and queries enable additional system efficiency enhancement.
- Iterative Improvement: Systems must evolve through ongoing optimizations following user input and business requirement developments.
