Before upgrading F5® BIG-IQ® Centralized Management, perform the following tasks.
|Reactivate the BIG-IQ system license.||You must do this on both the active and the secondary BIG-IQ if they are running in an HA pair. For specific instructions about how to reactivate a license, refer to the F5® BIG-IQ® Central Management: Licensing and Initial Setup guide.|
|Create a backup of the BIG-IQ system's current compressed user configuration set (UCS) and store it on a remote server.||The UCS file includes: system-specific configuration files; license, user account and password information; and SSL certificates and keys. You can use this backup if you want to restore to the previous version of BIG-IQ.|
|Decide which disk volume to install the upgrade on. At least two volumes are required to upgrade BIG-IQ.||If the machine you are upgrading does not have two volumes, you must create one using a CLI command. The upgrade task provides options for either case.|
Gather the following information:
|Required information||For my configuration|
|You'll need to create a passphrase for the Master Key. The passphrase must
|Get the discovery address you specified on the BIG-IQ system during setup. This is the same IP address that the peers in a high availability confirmation use to communicate. You can find this IP address on the BIG-IQ HA screen.|
|Get your BIG-IQ administrator and root passwords.|
|Get the name for the secondary HA BIG-IQ system if configured in an HA pair.|
If you're currently running a version of BIG-IQ prior to version 5.0, you must first upgrade to version 5.0 before you can upgrade to the latest version. For more information, refer to the guide titled, F5 BIG-IQ Centralized Management: Upgrading BIG-IQ to Version 5.0.
Upload the latest version of the BIG-IQ software image to your secondary BIG-IQ system to make it available for this upgrade.
Upload the latest version of the BIG-IQ software image to your primary BIG-IQ system to make it available for this upgrade.
Upgrade BIG-IQ to take advantage of the newest functionality and features.
Before you can enable statistics for BIG-IP® devices:
If you are running BIG-IP version 11.5.1 up to version 11.6.0, you might need root user credentials to discover and add the device to the BIG-IP devices inventory. You don't need root user credentials for BIG-IP devices running versions 11.6.1 - 12.x.
If you set up external storage for this logging node cluster in 5.1.and plan to retain that setup after you upgrade, continue setting up the external storage location. When you create DCD snapshots, they need to be stored on a machine other than the DCD. You define the location for the snapshot using the BIG-IQ® Centralized Management device.
After you upgrade the primary BIG-IQ® system as part of the minimal downtime workflow, confirm that it is back in service before you proceed.
