In which scenario do you need SAP expert sizing?

SAP expert sizing is required in scenarios such as:A. Migrating existing SAP ERP systems from AnyDB to run on SAP HANA, which involves complex migration considerations and the need to re-evaluate hardware and performance requirements under the new database architecture.C. Consolidating multiple SAP ERP source systems into one SAP ERP system on SAP HANA,which entails detailed planning to ensure the integrated system is sized appropriately to handle the combined workloads and data volume efficiently.Scenarios involving new customers to SAP ERP applications or carving out specific ERP functionalities do not necessarily require expert sizing unless they present unique or complex integration challenges that standard sizing tools and methods cannot address adequately.References= SAP HANA implementation guides and SAP technical documents on system migration and consolidation that discuss when expert sizing is essential.
