AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 95

A company is evaluating options to migrate its on-premises SAP ERP Central Component (SAP ECC) EHP 8 system to AWS. The company does not want to make any changes to the SAP versions or database versions. The system runs on SUSE Linux Enterprise Server and SAP HANA 2.0 SPS 05. The existing on-premises system has a 1 TB database.

The company has 1 Gbps or internet bandwidth available for the migration. The company must complete the migration with the least possible downtime and disruption to business.

Which solution will meet these requirements?

Answer options

• A. Install SAP ECC EHP 8 on Amazon EC2 instances. Use the same SAP SID and kernel version that the source system uses. Install SAP HANA on EC2 instances. Use the same version of SAP HANA that the source system uses. Take a full backup of the source SAP HANA database to disk. Copy the backup by using an AWS Storage Gateway Tape Gateway. Restore the backup on the target SAP HANA instance that is running on Amazon EC2.
• B. Install SAP ECC EHP 8 on Amazon EC2 instances. Use the same SAP SID and kernel version that the source system uses. Install SAP HANA on EC2 instances. Use the same version of SAP HANA that the source database uses. Establish replication at the source, and register the SAP HANA instance that is running on Amazon EC2 as secondary. After the systems are synchronized, initiate a takeover so that the SAP HANA instance that is running on Amazon EC2 becomes primary. Shut down the on-premises system. Start SAP on the EC2 instances.
• C. Install SAP ECC EHP 8 on Amazon EC2 instances. Use the same SAP SID and kernel version that the source system uses. Install SAP HANA on EC2 instances. Use the same version that the source system uses. Take a full offline backup of the source SAP HANA database. Copy the backup to Amazon S3 by using the AWS CLI. Restore the backup on a target SAP HANA instance that runs on Amazon EC2. Start SAP on the EC2 instances.
• D. Take an offline SAP Software Provisioning Manager export of the on-premises system. Use an AWS Storage Gateway File Gateway to transfer the export. Import the export on Amazon EC2 instances to create the target SAP system.

Correct answer: B

Explanation

Option B is optimal as it allows for replication and minimizes downtime, ensuring the business can switch to the AWS environment with minimal disruption. Other options involve longer processes like full backups and restores, which can lead to increased downtime and complexity in migration, making them less suitable for the company's requirements.
