This document provides a case study and requirements for planning the migration of Contoso's SAP systems from an on-premise environment to Azure. Contoso currently uses SAP ECC and BW and wants to migrate these workloads to Azure to reduce datacenter costs. The requirements include sizing estimates for migrating BW first within 3 months, then ECC, as well as plans for high availability, disaster recovery, backups, user access, and system integrations between Azure and on-premise. The document also discusses selection of Azure VMs, storage, and networking to meet SAP certification requirements and optimize performance for Contoso's SAP workloads.
