Why teams migrate from RDS to Cloud SQL

Good fit when

  • +Teams moving database workloads to GCP alongside compute migrations.
  • +Organizations that want managed PostgreSQL/MySQL with GCP-native auth and networking.
  • +Teams consolidating data services within Google Cloud.

Strengths

  • Cloud SQL integrates with GCP IAM for database authentication.
  • Automatic storage increases and maintenance windows are simpler to configure.
  • Native connectivity to Cloud Run, GKE, and other GCP services via private IP.

Tradeoffs

  • Some RDS-specific features (Multi-AZ with read replicas, Aurora compatibility) have no direct equivalent.
  • Parameter group tuning maps to database flags but with different naming.
  • Cross-region replication setup differs between RDS and Cloud SQL.

Migration notes

  • Use pg_dump/pg_restore or mysqldump for initial data transfer.
  • Set up DMS or logical replication for near-zero-downtime cutover.
  • Remap connection strings, SSL certificates, and IAM-based auth.
  • Verify PostgreSQL extension compatibility between RDS and Cloud SQL.
Typical effort:Medium (1-3 weeks)
