What to do next

After a DTS task is complete or a DTS instance is released, we recommend that you manually remove the CIDR blocks of DTS servers from the security settings of the source and destination database instances. This way, DTS can no longer access the source and destination databases. For more information, see the CIDR blocks of DTS servers section of the Add the CIDR blocks of DTS servers topic.

Remove the whitelist group whose name contains dts from the IP address whitelist of your Alibaba Cloud database instance.
In the security rules of your ECS instance, remove the security group whose name contains dts.
You must remove the CIDR blocks of DTS servers from the security settings of self-managed databases or databases hosted on third-party cloud platforms.
