Correct answer & explanation
✓
AWS DMS with ongoing replication
(AWS DMS with ongoing replication) is correct because AWS DMS can migrate data from Oracle to Aurora PostgreSQL with ongoing replication, enabling minimal downtime. Option A (AWS DataSync) is designed for file-based data transfers, not databases. Option C (AWS Snowball Edge) is for large-scale offline data transfer, not suitable for minimal downtime migration. Option D (AWS Schema Conversion Tool) helps assess schema compatibility and convert schemas, but does not perform the actual data migration.
