DMS is a fully managed service that enables the migration of database from one source to another, whether the source and target databases are in the cloud or on-premises. With DMS, you can:
- Quickly and securely migrate databases to AWS or other on-premises database
- The source database remains available during migration
DMS supports both homogeneous and heterogeneous migrations:
- Homogeneous migrations, where the source and target databases are of the same database technology. e.g. Oracle to Oracle
- Heterogeneous migrations, where the source and target databases are of different database technology. e.g. Microsoft SQL Server to Aurora
How does DMS work
You have a source database and you deploy the DMS on your EC2 instance, DMS will extract data from source database and insert the data into a target database.
