To meet the requirement of migrating the HANA database servers (rehosting/lift-and-shift) to Azure virtual machines while minimizing downtime, Azure Migrate is the appropriate tool.

• SCS (SAP Central Services): This is a server-level component. Azure Migrate (specifically the Server Migration tool) is the standard Azure service used to replicate on-premises virtual or physical servers to Azure VMs with minimal downtime during the cutover.
• HANA: While SAP-native tools like HSR (HANA System Replication) provide the lowest downtime for data, the question specifically asks for a tool to migrate the servers. Azure Migrate performs block-level replication of the entire server to an Azure VM.
• Why not others: Azure Database Migration Service does not support SAP HANA. S/4HANA Migration Cockpit is used for data/object migration, not server migration. HANA Cockpit is an administrative tool, not a migration engine for server-level moves.
