Changing Class of a DDM Node

Prerequisites

• You have logged in to the DDM console.
• The DDM instance is in the Running state.

Change node class during off-peak hours because services will be interrupted for a while during class changing.

Procedure

After a read-only group is created, the entry for changing node class will be moved to the operation column of the group.

1. In the instance list, locate the DDM instance whose node class you want to change and click its name. Click Change.
2. On the displayed page, select the required class.
3. Perform subsequent operations based on the instance's billing mode:
   • If the billing mode is Pay-per-use, click Submit.
   • If the billing mode is Yearly/Monthly, click Pay Now.

4. Confirm the configurations and click Submit.
5. Switch back to the instance list and check whether the status of the instance changes to Changing class. You can also view the change task at Task Center.
   

   • Once the change operation is performed, it cannot be undone. To change the class again, submit another request after the class change is complete.
   • Node class can be upgraded or downgraded.
