    Data Transmission Service:Release DTS instances

    Last Updated:Jul 17, 2026

    Manually release a pay-as-you-go DTS instance after its tasks are complete and the instance configurations are no longer needed to avoid extra costs.

    Usage notes

    • The instance must use the pay-as-you-go billing method.

      Note

      Subscription instances cannot be manually released. An unrenewed subscription instance is automatically released seven days after it expires.

    • Released DTS instances and their data cannot be recovered. Proceed with caution.

    • A synchronization or migration instance with a verification task appears in both its task list (Data Synchronization Tasks or Data Migration Tasks) and the Verification Task list. Exercise caution when performing operations.

    • DTS instances purchased during promotional events cannot be released.

    Release one or multiple pay-as-you-go instances

    1. Log on to the DTS console.

    2. In the navigation pane on the left, click Data Migration, Data Synchronization, Data Verification, or Change Tracking, based on the instance type.

    3. In the top navigation bar, select the region in which your instances reside.

    4. Release one or multiple DTS instances.

      • Release a single DTS instance

        In the Actions column of the target instance, choose More > Delete Task.

      • Release multiple DTS instances at a time

        Select the target instances and click Delete Task at the bottom of the page.

    5. In the confirmation dialog box, click OK.

    What to do next

    After a DTS task is complete or a DTS instance is released, remove the CIDR blocks of DTS servers from the security settings of the source and destination databases to prevent continued DTS access. For more information, see the CIDR blocks of DTS servers section of the Add the CIDR blocks of DTS servers topic.

    • Remove the IP whitelist group whose name contains dts from the IP address whitelist of each Alibaba Cloud database.

    • Remove the security group whose name contains DTS from the security rules of your ECS instance.

    • Remove the CIDR blocks of DTS servers from the security settings of self-managed databases or databases hosted on third-party cloud platforms.
