PAS-C01 SAP Migration Practice Question
A company is migrating an SAP ERP system to AWS. The SAP application runs on a Windows Server with an MSSQL database. The migration must be completed within a strict 4-hour downtime window. The current database is 500 GB. Which migration strategy should be used to meet the downtime requirement?

Correct answer & explanation
✓
Use an SAP-certified backup/restore tool (e.g., Commvault) to restore to Amazon EC2 with MSSQL
For migrating an SAP ERP system with MSSQL database to AWS within a 4-hour downtime window, using an SAP-certified backup/restore tool (e.g., Commvault) to restore to Amazon EC2 with MSSQL is the best approach. This method leverages native MSSQL backup and restore capabilities, which are optimized for large databases and can complete within the downtime window. Option A (SAP SWPM export/import) is typically slower and may exceed 4 hours. Option C (AWS DMS with ongoing replication) is not ideal because DMS may not fully support SAP-specific schemas and could introduce compatibility issues, and the cutover may not be faster than backup/restore. Option D (AWS CloudEndure Migration) is designed for server-level replication, not database-optimized transfer, and may not meet the strict time constraint.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use SAP SWPM export/import to migrate the database
Why it's wrong here
Export/import for MSSQL can take longer than 4 hours for 500 GB.
- ✓
Use an SAP-certified backup/restore tool (e.g., Commvault) to restore to Amazon EC2 with MSSQL
Why this is correct
Backup/restore can be faster and is supported for MSSQL on EC2.
- ✗
Use AWS DMS with ongoing replication, then cutover
Why it's wrong here
DMS may not fully support SAP-specific objects and could require schema conversion.
- ✗
Use AWS CloudEndure Migration to replicate the entire server
Why it's wrong here
CloudEndure replicates at block level but adds overhead; database consistency may be an issue.
