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