You can use Data Transmission Service (DTS) to read data from or write data to instances in an ApsaraDB for MyBase dedicated cluster. You can use this method to migrate data from a database that is not deployed in an ApsaraDB for Mybase dedicated cluster to an instance in the dedicated cluster. For example, you can migrate data from a self-managed MySQL database to a MyBase for MySQL instance by using DTS. The following table provides more details.
