Upgrade Management

Check Items

Check whether the target cluster is under upgrade management.

Solution

CCE may temporarily restrict the cluster upgrade due to the following reasons:

• The cluster is identified as the core production cluster.
• Other O&M tasks are either in progress or planned, such as the 3-AZ reconstruction on master nodes.
• If the cluster contains Docker nodes but their OSs are different from that of the node pool, reset these nodes and run the pre-upgrade check again.

To resolve this issue, contact technical support based on logs displayed on the console.
