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.|
After you prepare the data collection device (DCD) cluster for upgrade, use these procedures to upgrade the data collection devices in your cluster. Perform the following tasks for each DCD in the cluster.
You upload the BIG-IQ® version 5.3 software image to your DCD to make it available for this upgrade.
This is the first task you must perform on each DCD in the cluster to make sure that you do not lose any data during the upgrade. When you take the DCD you are about to upgrade offline, the BIG-IP® device routes the data to another DCD in the cluster.
|If you collect FPS alerts or IPsec events:||
|If you collect ASM event:||
|If you collect APM events:||You don't need to disable the DCD from the BIG-IP device. All you need to do is deactivate the service.|
You must perform this task for each DCD in the cluster to make sure that you minimize data loss during the upgrade. When you take the DCD you are about to upgrade off line, the BIG-IP® device routes the data to another DCD in the cluster.
The screen closes and BIG-IQ deactivates your services.
The upgrade process installs the new version of the software on one DCD. You must repeat this process for each DCD in your cluster.
After you upgrade a DCD as part of the minimum downtime workflow, you need to confirm that it is back in service before you proceed with upgrading the next DCD in the cluster.

After you upgrade a DCD and it is again a fully functioning member of the DCD cluster, you need it to start collecting data again.
The screen closes and BIG-IQ activates your services.
After you upgrade a DCD and reactivate data collection services, you need to start sending data to it again.
