Changing Class of a DDM Instance

Prerequisites

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

Change instance class during off-peak hours because services will be temporarily interrupted during class changing.

Procedure

If the read-only group function is not used, perform step 1 to change the class.

If the read-only group function is used, go to step 2 to change the class.

1. In the navigation pane, choose Instances; in the instance list, locate the DDM instance whose class you want to change, and choose More > Change Instance Class in the Operation column.
2. On the DDM console, choose Instances in the navigation pane. In the instance list, locate the DDM instance whose class you want to change, and click its name. On the displayed Basic Information page, click Change Instance Class at the Node Information area.
3. On the displayed page, view the current instance configuration and select the required instance class in the lower part of the page.
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.
   

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