Migrating Website Services Between Two AAD Instances

Application Scenarios

Once a website service is connected to AAD, you can switch its origin server IP address or origin server domain name to another AAD instance for protection by changing the corresponding high-defense IP resolution line.

The modified resolution lines take effect in about five minutes. To ensure normal service access, you are advised to perform this operation during off-peak hours.
