• 1. Export the AWS RDS database to a logical dump using pg_dump. 2. Transfer the dump file to a Google Cloud Storage bucket. 3. Import the dump into a new Cloud SQL instance using Cloud SQL import. 4. Update application connection strings to point to the new instance. 5. Verify data integrity and application functionality. 6. Switch DNS or load balancer to route traffic to the new instance. 7. Decommission the old AWS RDS instance.
