A company is migrating its SAP production system to AWS and needs to ensure that the migration does not exceed the allowed downtime window of 4 hours. The source database is 5 TB. Which migration strategy should be used?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Heterogeneous migration using AWS DMS with ongoing replication
Heterogeneous migration using AWS DMS with ongoing replication allows near-zero downtime by continuously replicating changes from the source to the target database during the migration, enabling a short cutover window. Option A is incorrect because homogeneous migration using AWS SCT and DMS is typically for same-database-engine migrations, but SCT is unnecessary for homogeneous, and the combination may not achieve the 4-hour window without ongoing replication. Option C is incorrect because AWS Snowball Edge is an offline data transfer method that involves shipping physical devices, which takes days to transfer 5 TB, exceeding the 4-hour window. Option D is incorrect because AWS Application Migration Service (MGN) is designed for server migration (rehosting), not database migration, and does not provide the database-level replication needed for this scenario.

- ✗
Homogeneous migration using AWS Schema Conversion Tool (SCT) and AWS DMS
Why it's wrong here
SCT adds time for schema conversion.
- ✓
Heterogeneous migration using AWS DMS with ongoing replication
Why this is correct
DMS with ongoing replication minimizes downtime.
- ✗
AWS Snowball Edge for offline data transfer
Why it's wrong here

- ✗
AWS Application Migration Service (MGN) replication
Why it's wrong here
