Can the Original Configuration Data Be Saved After I Unsubscribe from an AAD Instance?

No. After you unsubscribe from an AAD instance, it will not keep your original configuration data. Therefore, you need to connect your services to the newly-purchased AAD instance.

For details about unsubscription, see How Can I Unsubscribe from the AAD Service?.

To connect a service to the AAD, perform the following steps:

• If your system provides services through a domain name, you need to modify the DNS configuration to resolve the domain name to the CNAME record provided by Huawei Cloud.
• If your system provides services through an IP address, change the IP address to a high-defense IP address.
