Upgrading BIG-IQ Overview

Upgrading BIG-IQ to the latest version

What BIG-IQ setup does this upgrade process support?

This process supporting upgrading BIG-IQ version 5.4.0 and later without a data collection device (DCD) cluster to the latest version.
If your BIG-IQ is not currently running one of these versions, or includes a DCD, refer to the supported upgrade paths section in the release notes for this BIG-IQ version.

What happens during a BIG-IQ upgrade

This example represents a BIG-IQ in a high availability configuration. During the upgrade, the BIG-IQ suspends BIG-IP device management. This can result in a downtime of services. The amount of downtime depends on the size of your system's setup. BIG-IQ services resume when the active BIG-IQ is upgraded and restarted.

Tasks to complete before you start the upgrade process

Before upgrading F5 BIG-IQ Centralized Management, complete these tasks.
Tasks
Additional information
Download the latest BIG-IQ software image and Pre-upgrade Check tool from the F5 Downloads site.
To ensure that the pre-upgrade script runs correctly, make sure you always download the latest version of the tool from
downloads.f5.com
.
Prepare your statistics for the upgrade process
See Prepare statistics for upgrade. If your BIG-IQ CM is in an HA pair, ensure that this process is completed on each node.
Run the pre-upgrade check script on the primary BIG-IQ by typing the following commands:
  1. #
    cd /shared/scripts/preUpgradeChecks
  2. #
    ./preUpgradeCheck
This script verifies the following for BIG-IQ:
  • Disk assessment and partition size.
  • Health checks
  • Licensing verification.
  • CPU and memory assessment.
For additional detail about this script, refer to the AskF5 article K15988343 on
support.f5.com
.
Depending on the version of BIG-IQ software you are upgrading from, the connectivity requirements for your system may be different in the version you are upgrading to. Refer to the AskF5 Knowledge Center article
K15612: Connectivity requirements for the BIG-IQ system
on
support.f5.com
to confirm that the ports you need are configured correctly.
Additional information on network connectivity requirements is available in the
Planning and Implementing a BIG-IQ Deployment
on
support.f5.com
Deploy any staged configuration changes to your managed BIG-IP devices.
When addressing configuration conflicts for each BIG-IP device, F5 recommends you use BIG-IP to override the configuration settings stored on BIG-IQ.
Decide which disk volume you want to install the BIG-IQ software on. You must have at least two volumes to upgrade BIG-IQ.
If the BIG-IQ you are upgrading doesn't have two volumes, refer to:
K17406: Using the tmsh utility to create a new software volume for installing a new image or hotfix on the BIG-IQ system
at: https://support.f5.com/csp/article/K17406
If you are currently using a self-IP address for device discovery, make a note of that IP address.
You'll need to enter that IP address when you perform setup after you upgrade and reboot the BIG-IQ system.
Upgrade all managed BIG-IP devices to version 12.1 or later.
For you to manage BIG-IP devices from BIG-IQ Centralized Management, the BIG-IP devices must be running version 12.1 or later.
Run the following command to view all daemons running on the BIG-IQ, and their status:
admin@(ip-10-1-1-4)(cfg-sync Standalone)(Active)(/Common)(tmos)# show /sys service
.
Make a note of the daemons running on BIG-IQ and their status. After the upgrade, verify that all daemons are running as expected.
