There are two workflows you can follow to upgrade your BIG-IQ® Logging Node cluster. Before you start the upgrade process, decide which workflow is appropriate for you.
A Logging Node cluster is made up of all of your Logging Nodes, the BIG-IQ® that you use to manage them, and any BIG-IQ peer devices. If you use a Logging Node cluster to store and manage your alerts and events, there are additional steps in the upgrade process.
