    • Unknown: The migration status of the cluster cannot be determined.

    Rebalancing

    Description: Indicates that the Couchbase cluster is rebalancing its data across nodes.

    • Unknown: The validity of the cluster spec cannot be determined.

    MixedMode

    Description: The Couchbase cluster is running nodes on two different Couchbase Server versions.

    Possible Values:
