Before upgrading F5® BIG-IQ® Centralized Management, perform the following tasks.
|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 in the event you want to restore to the previous version of BIG-IQ.|
|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.|
|Deploy any staged configuration changes to your managed devices.||
This step is required only if you are going to use the script to re-discover and re-import BIG-IP devices and services after the upgrade (as outlined in the section titled, Re-discover devices and re-import services in bulk using a script).You must deploy configuration changes you have staged for your devices if you use this script, because they'll be overwritten on BIG-IQ after you run the script. If you'd rather re-discover devices and re-import services from the BIG-IQ user interface (instead of in bulk) so you can address any potential configuration conflicts for each BIG-IP device, refer to the section titled, Re-discover devices and re-import services from the user interface.
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 version 5.3. For more information, refer to the guide titled, F5 BIG-IQ Centralized Management: Upgrading BIG-IQ to Version 5.0.
If you're upgrading BIG-IQ Data Collection Device clusters, refer to the guide titled, F5 BIG-IQ Centralized Management: Upgrading Data Collection Device clusters to version 5.3.
Upgrade the BIG-IQ primary to take advantage of the newest functionality and features.
