AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 130

A company is running an SAP on Oracle system on IBM Power architecture in an on-premises data center. The company wants to migrate the SAP system to AWS. The Oracle database is 15 TB in size. The company has set up a 100 Gbps AWS Direct Connect connection to AWS from the on-premises data center.
Which solution should the company use to migrate the SAP system MOST quickly?

Answer options

• A. Before the migration window, build a new installation of the SAP system on AWS by using SAP Software Provisioning Manager. During the migration window, export a copy of the SAP system and database by using the heterogeneous system copy process and R3load. Copy the output of the SAP system files to AWS through the Direct Connect connection. Import the SAP system to the new SAP installation on AWS. Switch over to the SAP system on AWS.
• B. Before the migration window, build a new installation of the SAP system on AWS by using SAP Software Provisioning Manager. Back up the Oracle database by using native Oracle tools. Copy the backup of the Oracle database to AWS through the Direct Connect connection. Import the Oracle database to the SAP system on AWS. Configure Oracle Data Guard to begin replicating on-premises database log changes from the SAP system to the new AWS system. During the migration window, use Oracle to replicate any remaining changes to the Oracle database hosted on AWS. Switch over to the SAP system on AWS.
• C. Before the migration window, build a new installation of the SAP system on AWS by using SAP Software Provisioning Manager. Create a staging Oracle database on premises to perform Cross Platform Transportable Tablespace (XTTS) conversion on the Oracle database. Take a backup of the converted staging database. Copy the converted backup to AWS through the Direct Connect connection. Import the Oracle database backup to the SAP system on AWS. Take regularly scheduled incremental backups and XTTS conversions of the staging database. Transfer these backups and conversions to the AWS target database. During the migration window, perform a final incremental Oracle backup. Convert the final Oracle backup by using XTTS. Replay the logs in the target Oracle database hosted on AWS. Switch over to the SAP system on AWS.
• D. Before the migration window, launch an appropriately sized Amazon EC2 instance on AWS to receive the migrated SAP database. Create an AWS Server Migration Service (AWS SMS) job to take regular snapshots of the on-premises Oracle hosts. Use AWS SMS to copy the snapshot as an AMI to AWS through the Direct Connect connection. Create a new SAP on Oracle system by using the migrated AMI. During the migration window, take a final incremental SMS snapshot and copy the snapshot to AWS. Restart the SAP system by using the new up-to-date AMI. Switch over to the SAP system on AWS.

Correct answer: C

Explanation

The correct answer is C because it utilizes the Cross Platform Transportable Tablespace (XTTS) method, which allows for efficient migration of large Oracle databases. Options A and B involve additional complexities and downtime, while D relies on snapshots that may not be as effective for large-scale migrations like the one described.
