Question
A company has been using SAP S/4HANA with terabytes of data on premises to run its financial system. The company needs to migrate the SAP landscape to AWS. The on-premises data center is connected to an AWS Region through a 1 Gbps AWS Direct Connect connection. The company's networking team has ensured that the full bandwidth is available for the SAP migration project. An SAP solutions architect needs to migrate the on-premises systems by implementing a solution that minimizes downtime. Which solution will meet these requirements?
Options
- AUse Amazon S3 Transfer Acceleration to perform backup and restore.
- BUse SAP Software Update Manager (SUM) Database Migration Option (DMO) with System Move
- CUse SAP HANA system replication.
- DUse SAP classical export/import (R3load based).

Explanation
SAP HANA System Replication (HSR) provides continuous, synchronous or asynchronous data replication at the database level, making it the optimal choice for near-zero-downtime migration. The process works by: (1) setting up the AWS target as a secondary HSR node replicating from the on-premises primary, (2) allowing initial sync and then ongoing delta sync over the Direct Connect link, and (3) performing a controlled failover/takeover with only brief downtime during switchover. Option A (S3 Transfer Acceleration) is a backup/restore approach that requires extended downtime for restoration. Option B (SUM DMO with System Move) is a valid migration path but involves more downtime since it converts the database schema during migration. Option D (classical R3load export/import) is the slowest approach and causes the most downtime since the source system must be stopped during export.
