The data transmission service allows you to migrate data between homogeneous or heterogeneous data sources in business scenarios such as database upgrade, cross-instance data migration, database splitting, and database scaling.
To prepare for, purchase, configure, and manage a data migration project, perform the following steps:
Prepare for data migration.
The data transmission service has the privilege to access cloud resources. For more information, see Grant privileges to roles for data transmission.
Create dedicated database users for data migration in the source and destination, and grant required privileges to the users. For more information, see Create a database user.
Create data sources.
In the left-side navigation pane, choose Data Transmission > Data Source Management. On the page that appears, create source and destination data sources. For more information, see Create a data source.
Purchase a data migration project.
Purchase a data migration project of the corresponding type based on your business needs. For more information, see Purchase a data migration project.
Configure the data migration project and start it after the precheck is passed.
For more information, see the topics for data migration projects of the corresponding type.
View the status of the data migration project.
After the data migration project is started, it will be executed based on the selected migration types. For more information, see View the details of a data migration project.
(Optional) Stop and release the data migration project.
After the data migration project is completed, if data no longer needs to be synchronized from the source database to the destination database, you can release the current data migration project. For more information, see Stop and release a data migration project.
