Correct answer & explanation
✓
Schema Conversion Tool (SCT)
Database Migration Service (DMS) handles data migration and can assist with schema conversion for homogeneous migrations. However, for heterogeneous migrations like SQL Server to PostgreSQL, Schema Conversion Tool (SCT) is needed for schema conversion. Cloud SQL is the target. BigQuery and Cloud Spanner are not applicable here.
