Key features

Key features

Easy to use

A guided experience takes you through migration of MySQL, PostgreSQL, SQL Server, and Oracle databases and offers built-in, customized source configuration information, schema and code conversion, and setup of multiple secure networking connectivity options. Database Migration Service leverages native replication capabilities for highly accurate, high-fidelity migrations, and you can run a validation before the migration to ensure migration success.

Gemini in Database Migration Service

Make database migration simpler and faster with AI-powered assistance. With the help of Gemini in DMS, in preview, you can review and convert database-resident code like stored procedures, triggers, and functions to a PostgreSQL compatible dialect. To upskill and retrain SQL developers, explainability enables a side-by-side comparison of dialects, along with a detailed explanation of code and recommendations.

Integrated conversion and migration

Modernize your legacy Oracle workloads by migrating them to PostgreSQL. A built-in conversion workspace reduces the manual effort of heterogeneous migrations, and the Gemini-assisted conversion process guides you through schema and code conversion and highlights any conversion issues for your review. The conversion workspace is available for migrations from Oracle to Cloud SQL and AlloyDB.

Serverless experience

Eliminate the operational burdens of database migration. There are no migration servers to provision, manage, or monitor, and auto-scaling ensures high-performance, uninterrupted data replication at scale. The entire process is done with minimal downtime, from the initial snapshot of the source database to continuous replication of changes.

Secure by design

Rest easy knowing your data is protected during migration. Database Migration Service supports multiple secure, private connectivity methods to protect your data in transit. Once migrated, all data is encrypted by default, and Google Cloud databases provide multiple layers of security to meet even the most stringent requirements.
