Changing a Private IP Address

Scenarios

After migrating a database from an on-premises environment or another cloud platform to a DDS instance, you may need to change the instance's private IP address. DDS allows you to change private IP addresses, helping you reduce migration costs.

Precautions

Changing the private IP address of a node will invalidate the previous private IP address. If an EIP is bound to the node, do not unbind the EIP during the change of the private IP address. After the change, the new private IP address is bound to the EIP.

2. Click in the upper left corner and select a region and a project.
