After you prepare the data collection device (DCD) cluster for upgrade, use these procedures to upgrade the DCDs in your cluster. Perform the following tasks for each DCD in the cluster.
Before upgrading the F5® BIG-IQ® Centralized Management data collection device, perform these tasks.
|Re-activate the BIG-IQ system license.||You must do this for each data collection device in the cluster. For specific instructions about how to reactivate a license, refer to the F5® BIG-IQ® Central Management: Licensing and Initial Setup guide.|
|Decide which disk volume you want to install the upgrade on. You must have at least two volumes to upgrade BIG-IQ.||If the machine you are upgrading does not have two volumes, you must create one using a sequence of tmsh commands. The upgrade task provides options for either case.|
You upload the BIG-IQ® version 5.3 software image to your DCD to make it available for this upgrade.
The upgrade process installs the new version of the software on one DCD. You must repeat this process for each DCD in your cluster.
