Migrate Cloud SQL for MySQL to Amazon Aurora and Amazon RDS for MySQL Using AWS DMS

Database Blog

This article provides a comprehensive guide for migrating Cloud SQL for MySQL 8+ to Amazon RDS for MySQL or Aurora MySQL-Compatible using AWS DMS over Site-to-Site VPN.

  • AWS DMS supports three homogeneous migration approaches: full load, CDC, or combined full load and CDC
  • Site-to-Site VPN offers cost-effective cross-cloud connectivity with up to 1.25 Gbps standard or 5 Gbps large bandwidth tunnels
  • MySQL 5.x retirement requires attention to GTID versus binary log replication considerations for MySQL 8+
  • AWS DMS uses binary log-based replication, not GTIDs, requiring manual restart if source fails over
  • Migration process includes preparing source/target databases, creating data providers, configuring IAM roles, and running DMS tasks
  • Validation involves comparing row counts and spot-checking data between source and target databases
  • For multi-terabyte databases, AWS recommends AWS Interconnect–multicloud for higher throughput and lower latency

This guide enables database administrators to migrate MySQL databases from GCP to AWS efficiently using native tools and serverless DMS infrastructure.
