Installing and upgrading BIG-IQ System software
Before you perform an initial BIG-IQ System software installation, or software upgrade, you must perform the following tasks:
- Activate, or reactivate, your current license to ensure that you have a valid service check date.
- Download the ISO file for the upgrade from F5 Downloads to /shared/images on BIG-IQ System. If you need to create this directory, use the exact name /shared/images.
- For upgrades only, create a backup of the user configuration set (UCS), locate it in the /var/local/ucs directory on the source installation location, and copy the UCS file to another system for safe keeping.
Use this procedure when you are ready to perform an initial BIG-IQ System software
installation or upgrade a to a more recent software version.
- Log in to BIG-IQ System with your administrator user name and password.
- At the top of the screen, click Configuration.
- On the BIG-IQ Systems panel, expand Management Group or HA Peer Group by clicking the arrow next to it.
- Click the gear icon next to localhost, and then click Properties.
- Click Software Update.
- Click the Update button.
- From the Software Image list, select the new image or browse to the location to which you saved it.
- From the Install Location list, select the volume to which you want to install the image.
-
For the Options setting, select one:
- To automatically reboot the BIG-IQ System to the specified volume immediately after the software is installed, select Reboot after Live Install.
- To manually reboot the BIG-IQ System at another time from the screen, select Set Default Boot Location.
- Click the Apply button.
BIG-IQ System installs the selected software. For upgrades, BIG-IQ System also rolls
forward the UCS file.
About UCS files
The configuration details of managed devices (including the BIG-IQ system itself) are contained in a compressed user configuration set (UCS) file. The UCS file contains all of the information required to restore a device's configuration, such as:
- System-specific configuration files
- License
- User account and password information
- SSL certificates and keys
You can back up devices at regularly scheduled intervals and select the amount of time to save the backups.
Creating a backup UCS file
It is best practice to create a backup of the UCS file for each device in your
network, including the BIG-IQ system itself, on a regular basis
and before performing a software upgrade. The UCS file backup provides your network with
added stability in the event that a system needs to be restored.
This UCS backup file is now available for restoration.
