What migration scenarios does AWS DMS support?

AWS DMS supports homogeneous migrations (MySQL to MySQL, PostgreSQL to PostgreSQL) and heterogeneous migrations (Oracle to PostgreSQL, SQL Server to MySQL). We use DMS alongside AWS Schema Conversion Tool (SCT) for complete cross-platform migrations.

How do you minimize downtime with AWS DMS?

We use AWS DMS ongoing replication (CDC) to keep source and target in sync during migration. This allows extended testing of the target environment while the source continues serving production traffic, resulting in cutover windows of minutes rather than hours.

What are common AWS DMS pitfalls and how do you avoid them?

Common pitfalls include LOB handling issues, replication lag under heavy write loads, and task failure recovery. We pre-configure DMS tasks with proper LOB settings, monitoring, and error handling, and implement validation jobs to verify data consistency throughout the migration.

AWS DMS · Change Data Capture

AWS Database Migration Service

In short: AWS DMS (Database Migration Service) is a managed AWS service that migrates databases to AWS with minimal downtime. It also supports ongoing change data capture (CDC) — continuously replicating inserts, updates, and deletes from a source database to a target in near real time.

Migrate your databases to AWS quickly and securely with minimal downtime. Our AWS DMS expertise ensures smooth transitions and continuous data replication.
