SAP BW: Enterprise Data Warehousing for SAP and Non-SAP Source Integration
As SAP customers face the impending end of mainstream maintenance for SAP BW 7.5 in 2027, organizations are evaluating migration paths to SAP BW/4HANA, SAP Datasphere and SAP Business Data Cloud to modernize their data warehousing infrastructure. SAP Business Warehouse remains a workhorse for integrating, transforming and consolidating business data from SAP and non-SAP sources, but many enterprises are transitioning to cloud-ready architectures that preserve existing data models while unlocking AI and machine learning capabilities. SAPinsider analysis of BW modernization shows that organizations migrating legacy SAP BW environments to SAP Business Data Cloud can optimize costs through zero-copy data sharing and simplify governance across SAP and non-SAP sources.
What Is SAP BW?
SAP Business Warehouse (SAP BW) is an enterprise data warehousing platform that enables organizations to integrate, extract, transform, clean and consolidate data from SAP applications and external data sources for reporting, business intelligence and analytics. SAP BW is available in multiple versions including SAP BW 7.5 (with mainstream maintenance ending in 2027), SAP BW/4HANA (next-generation built on SAP HANA with cloud deployment options), and SAP BW on HANA (combines traditional BW with in-memory performance).
What Use Cases Are Referenced?
SAP BW Migration to Business Data Cloud Preserves Data Models
Organizations migrating legacy SAP BW to SAP Business Data Cloud can leverage zero-copy data sharing between SAP BW, SAP Datasphere and SAP Databricks, preserving existing investments while gaining cloud scalability and advanced analytics capabilities.
BW/4HANA In-Place Migration Upgrades Existing Infrastructure
The in-place migration strategy upgrades an existing SAP BW system directly to SAP BW/4HANA, maintaining the same system ID while redesigning applications and cleaning up obsolete objects to align with the modern BW/4HANA architecture.
Cloud Migration Unlocks New Analytics and AI Capabilities
Migrating SAP BW from on-premise to cloud platforms opens access to new data sources and advanced analytics including artificial intelligence and machine learning, and scalability that enhances data accessibility across the enterprise.
BW on HANA Delivers In-Memory Performance Gains
SAP Business Warehouse on HANA combines traditional BW data warehousing with in-memory database to deliver excellent query performance, reduced data latency and accelerated in-memory planning capabilities for real-time decision-making.
Data Warehousing Supports S/4HANA Clean Core Initiatives
As organizations migrate to S/4HANA, SAP BW 7.5 will reach the end of mainstream maintenance in 2027, prompting users to consider transitioning to modern architectures that decouple reporting from the ERP system while maintaining historical data access.

SAP BW Migration Done RightOrganizations running SAP BW 7.5 or older face an urgent imperative to migrate off a soon-to-be-unsupported platform, but treating this as a technical lift-and-shift leads to expensive projects that replicate existing data chaos on newer systems.
By instead treating SAP BW migration as a chance to modernize and encapsulate business logic into governed, reusable data products, organizations can build an AI-ready data platform that preserves critical intelligence while unlocking new analytical capabilities.
