As part of preparing to upgrade your
Logging Node, you must shut down the cluster so that upgraded devices and devices that
have not yet upgraded do not communicate during the upgrade.

device in the cluster (that is, each Logging Node device, the BIG-IQ® Centralized Management device, and the BIG-IQ HA
Once you have stopped the cluster
for each device, you can proceed with the cluster upgrade.
