Data Transmission Service lets you download the configuration of migration objects from a data migration task. You can also import a CSV file to automatically configure and confirm these objects. This feature lets you save task configurations and quickly configure multiple objects at once. The import feature is useful for batch operations, such as renaming and configuring hundreds of objects.
Download object configurations
After you create a data migration task and specify the migration objects, you can download their configuration. This configuration includes source database names, source table names, destination database names, destination table names, column mappings, and row filter conditions.
Log on to the OceanBase Management Console .
In the navigation pane on the left, click Data Transmission Service > Data Migration.
On the Data Migration page, click the name of the target data migration task.

On the task details page, click ... > Download Object Configuration in the upper-right corner.
ImportantYou cannot download object configurations for data migration tasks that use the Matching Rules method to select migration objects.

Import object configurations
Data Transmission Service lets you import a CSV file to perform operations such as renaming databases and tables or setting row filter conditions. You can download the object configuration from an existing task or a CSV template, modify it as needed, and then import it.
If you edit the file in Excel, save it as a comma-separated values (CSV) file before you import it.
The imported CSV file must include the following columns: source database name, source table name, destination database name, destination table name, column mapping, and row filter conditions.
Log on to the OceanBase Management Console and purchase a data migration task.
