This topic describes how to migrate an OBProxy cluster from one OceanBase Cloud Platform (OCP) cluster to another.
Notice
After an OBProxy cluster is migrated from an OCP cluster, it is no longer managed by the OCP cluster. Proceed with caution.
Prerequisites
You have logged on to the OCP console and are assigned the
OBPROXY_MANAGERrole.The cluster to be migrated is in the RUNNING state.
If other services are deployed on the host where the OBProxy cluster is deployed, you cannot delete this host from the OCP cluster when you migrate the OBProxy cluster.
Procedure
OCP provides two entries for you to migrate an OBProxy cluster:
Entry 1: Go to the OBProxy page, locate the target OBProxy cluster in the cluster list, click More in the Actions column, and choose Migrate Cluster.
Entry 2: Go to the Overview page of the target OBProxy cluster, hover the pointer over the More icon, and click Migrate Cluster.
The following procedure takes Entry 2 as an example.
Log on to the OCP console.
In the left-side navigation pane, click OBProxy.
In the Clusters list, click the target OBProxy cluster to go to its Overview page.
Hover the pointer over the More icon and then click Migrate Cluster.
In the dialog box that appears, perform the following operations:
Export the information about the load balancers used by the OBProxy cluster.
You can click Export or Move Out to export relevant load balancer data. If you want to retain the original load balancer configurations in the OBProxy cluster, you can import this file when you take over the OBProxy cluster. This way, you do not need to configure the same load balancer information again. For more information, see Take over an OBProxy.
Select the host where the cluster is deployed and delete it from the OCP cluster.
Before you take over the OBProxy cluster in a new OCP cluster, you must delete the host from the original OCP cluster. You can also delete the host on the Hosts page. For more information, see Delete a host.
Enter move out in the textbox and click Move Out to submit a task to migrate the OBProxy cluster.
In the dialog box that appears, click View Task to view the migration progress.
After the task status changes to Completed, and the OBProxy cluster disappears from the cluster list on the OBProxy page, the OBProxy cluster is migrated.
