In scenarios where existing SAP ERP systems are being migrated from AnyDB to SAP HANA, an SAP expert sizing is needed to ensure optimal performance and resource allocation. This also applies when consolidating multiple SAP ERP source systems into a single SAP ERP system on SAP HANA, as it requires careful planning and sizing to handle the combined load effectively. Carving out specific functionality typically does not require the extensive planning involved in migrating or consolidating entire systems. Additionally, new customers to SAP ERP applications are likely to need general implementation support rather than specific expert sizing.
