Learn how to use AI agents with AWS DMS Schema Conversion to orchestrate SQL Server to Amazon Aurora PostgreSQL schema conversion through natural language. See how the conversion engine processes T-SQL, how the agent drives the workflow, and how to interpret and resolve CRITICAL action items using decision frameworks for common incompatibilities.

Learn how to configure Oracle Materialized Views with Fast Refresh and materialized view logs to enable efficient, incremental AWS DMS change data capture (CDC) replication. This approach eliminates full-reload overhead and achieves near real-time migration of large, multi-table joined views to AWS.

Learn how to use Oracle SQLcl, a lightweight alternative to the full Oracle Client, to create and manage an Oracle Wallet for SSL connections between AWS DMS and Amazon RDS for Oracle. This post walks through installing SQLcl, adding certificates, testing the SSL connection, and configuring the AWS DMS endpoint.

AWS DMS uses exponential backoff for recoverable errors, and default settings can let a change data capture (CDC) task retry silently for up to 30 minutes before failing. This post shows how to tune four recoverable-error settings so CDC tasks fail within minutes, and how to pair them with Amazon EventBridge and Amazon CloudWatch alerts.

Migrate a self-managed PostgreSQL database on Amazon EC2 to Amazon RDS for PostgreSQL or Amazon Aurora PostgreSQL-Compatible Edition using the auto-migration capability in the Amazon RDS console, powered by AWS Database Migration Service (AWS DMS) homogeneous data migrations.

Managing payment infrastructure at scale presents unique challenges that impact both performance and operational efficiency. In this post, we share the technical and operational challenges Nubank faced with self-managed PostgreSQL, the evaluation criteria they established for selecting database solutions, and the results from their successful migration to Amazon Aurora PostgreSQL-Compatible Edition. Nubank achieved up to 1,900x query performance improvements in specific cases.

AWS Database Migration Service Schema Conversion (DMS SC) converts database objects across heterogeneous systems such as Oracle or SQL Server to PostgreSQL or MySQL. In this post, we show you how DMS SC, with generative AI capabilities, elevates the code conversion experience.

Starting today, you can use AI agents to orchestrate entire AWS DMS Schema Conversion (DMS SC) workflows through natural language. An AI agent manages the full lifecycle, including creating migration projects, browsing source metadata, converting schemas, generating assessment reports, and exporting results, all from a conversational prompt.

In this post, you learn how to set up CDC-only reverse replication from Amazon Relational Database Service (Amazon RDS) for Db2 back to your on-premises AIX Db2 instance using AWS Database Migration Service (AWS DMS).

In this post, we show you how long-running transactions affect AWS Database Migration Service (AWS DMS) change data capture (CDC) latency, walk through monitoring approaches for Oracle, PostgreSQL, MySQL, and SQL Server, and provide ready-to-use scripts to identify and resolve problematic transactions before they impact your replication performance.
