Can I Stop a CSS Cluster?

No. If you need to migrate a cluster, you can suspend the services of the old cluster and delete it after the migration is complete. You can perform the following operations:

• If the cluster version supports flow control, you can use one-click traffic blocking to block all the traffic, except the traffic of the O&M interface on the node.
• If your cluster version in use does not traffic control, you can disable the read and write of all service indexes instead. For example, if all service indexes start with log, run the following command on the Dev Tools page of Kibana:

  PUT log*/_settings
  {
    "index.blocks.read": true,
    "index.blocks.write": true,
    "index.blocks.metadata": true
  }
