Data Transmission Service helps you migrate data with virtually no downtime. All data changes to the source database that occurs during the migration is continuously replicated to the target, allowing the source database to remain fully operational during the migration process. After the database migration is complete, the target database will remain synchronized with the source for if you choose, allowing you to switch over the database at a convenient time.

DTS can migrate your data to and from most of the widely used commercial and open source databases. It supports homogeneous migrations such as MySQL to MySQL, as well as heterogeneous migrations between different database platforms, such as Oracle to MySQL. Migrations can be from on-premises databases to RDS or ECS, databases running on ECS to RDS, or vice versa, as well as from one RDS database to another RDS database. DTS supports multiple transmission modes, such as data migration, real time data replication, and change data subscription.

Provides crucial instance information like replication delay, transmission status, and consumption delay in real time so that you can monitor and protect business critical applications. Try out over 40 products for free.

DTS manages all the complexities of the migration process including automatically replicating data changes that occur in the source database during the migration process.

DTS continually monitors the source and target databases, when the connection changes, DTS dynamically modifies the connection in order to optimize performance.

DTS's high performance supports replication in parallel, and supports multiple network optimization features, such as data compression and packet retransmission.
