What you need to do before you upgrade BIG-IQ from version 5.x to 5.4

Before upgrading F5® BIG-IQ® Centralized Management, perform the following tasks.

Tasks Additional information
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.
Deploy any staged configuration changes to your managed devices. Deploy configuration changes you have staged for your devices. When addressing configuration conflicts for each BIG-IP device, we recommend you use BIG-IP to override the configuration settings stored on BIG-IQ. Refer to the section titled, Re-discover devices and re-import services from the user interface.

If you are currently using a self-IP address for device discovery, make a note of that IP address.

You'll need to enter it when you perform setup after you upgrade and reboot the BIG-IQ system.

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 5.4. For more information, refer to the guide titled, F5 BIG-IQ Centralized Management: Upgrading BIG-IQ to Version 5.0 .

Remove the secondary BIG-IQ from the HA pair

If the F5® BIG-IQ® Centralized Management system is configured in an HA pair, you must remove the secondary BIG-IQ system before you upgrade it.
  1. Log in to the primary BIG-IQ with your admin user name and password.
  2. At the top of the screen, click System.
  3. On the left, click BIG-IQ HA.
  4. Click Remove Secondary.
    A dialog box opens, prompting you to confirm that you want to remove the HA secondary device from this group.
  5. Click Remove to confirm that you want to take the HA secondary device out of the group.
    The system logs you out of the BIG-IQ while it removes the secondary device.
  6. Log back in to the primary BIG-IQ with your admin user name and password.
    For a while, both the primary and the secondary BIG-IQ devices continue to display. After a few minutes, the screen updates to display a single standalone device.

Upload the BIG-IQ software image to the secondary BIG-IQ system

Before you can upload the software image to your secondary BIG-IQ® system, you must have first downloaded it from the F5 Downloads site.

Upload the latest version of the BIG-IQ software image to your secondary BIG-IQ system to make it available for this upgrade.

  1. At the top of the screen, click System.
  2. On the left, expand THIS DEVICE > Software Management , and then click Available Images.
    The Available Images screen lists the software image files that are available for installation on this BIG-IQ system.
  3. Click the Upload Image button.
  4. Click the Choose File button and go to the location to which you downloaded the image, and click the Open button to upload it to BIG-IQ.
  5. Click the Upload button.
    The screen refreshes to display the progress of the upload.
When the image is finished uploading, it shows in the Available Images list.

Install the latest version of BIG-IQ software on the HA peer

Note: If the machine you are upgrading does not have two volumes, you must create one using a CLI command. The following steps provide options for either case.
Install the latest version of the BIG-IQ software on the peer BIG-IQ system so it will be running the same version as the primary BIG-IQ system you are upgrading.
  1. Log on to the system you are going to establish as the secondary BIG-IQ system's command line as root and type the following command: /usr/bin/clear-rest-storage.
    Although this step is not required, it clears the database storage on the system so the upgrade goes more quickly. After you upgrade both peer systems and re-establish the HA pair, the peer BIG-IQ will synchronize its database with this BIG-IQ system and repopulate the database.
  2. Log on to the system you are going to establish as the secondary BIG-IQ system's user interface.
  3. If you ran the clear-rest-storage command, complete the setup wizard. Otherwise, continue to the next step.
  4. At the top of the screen, click System Management.
  5. On the left, click BIG-IQ DEVICES > BIG-IQ HA .
  6. On the left, click Software Version.
  7. Click the Update button.
  8. From the Software Image list, select the image you want to install.
  9. From the Target Volume list, select the volume you want to install the image on.
    Note: If the Target Volume list is empty, the machine you are upgrading does not have a second volume available for you to install the upgrade. You must create one to proceed.
    • If you selected a target volume, complete the remaining steps to finish the upgrade.
    • If you do not have a second volume, use the following procedure to install the upgrade for this machine:
      • Use SSH to log in to the machine you want to upgrade. You must log in as root to perform this procedure.
      • Navigate to the folder where you install software using the command: cd /shared/images
      • Install the upgrade to a new volume by running one of the following commands:
        • If you are upgrading a virtual machine: tmsh install sys software image <full name of the iso file> volume hd1.2 create-volume reboot
        • If you are upgrading a BIG-IQ 7000 series platform: tmsh install sys software image <full name of the iso file> volume md1.2 create-volume reboot
      • While the system installs the upgrade to the new volume, you can check on the status of the upgrade using the command: tmsh show sys software status.
      • When the upgrade finishes installing, the machine reboots. Proceed to the next to the last (login) step in this task.
  10. To prompt BIG-IQ to reboot into the new software installation volume, select the Reboot into Target Volume check box.
  11. Click the Apply button.
    A popup screen opens, prompting you to confirm the installation.
  12. Click the Continue button.
  13. Wait while BIG-IQ loads the new software and reboots.
    Depending on your configuration and the number of devices you are managing, this could take up to an hour. During this time, it is important that you not interrupt the installation process by restarting services or the server.
  14. Log in to the BIG-IQ that will be the secondary BIG-IQ system to confirm that the upgrade succeeded and complete the setup wizard.
    To complete the setup task, you must supply a master key pass phrase that all devices in the logging node cluster must share. Make note of the phrase you use. Each logging node, as well as the primary and secondary BIG-IQ systems must use this phrase before they can join the cluster.
  15. If needed, extend the /var partition.
    The default size of the /var file system in a newly installed or upgraded node is 30 GB. This amount of available storage might not be enough to store your data. If you previously extended your disk space, you'll need to do it again after you upgrade, as explained in K16103: Extending disk space on BIG-IQ Virtual Edition.
    Important: Upgrading a node requires at least two volumes, so be sure you can extend the /var file system on both volumes to the same size; otherwise, upgrades might fail.

Upload the latest version of the BIG-IQ software image

Before you can upload the software image to the BIG-IQ® system, you must have first downloaded it from the F5 Downloads site.

If you previously extended your disk space, you'll need to do it again after you upgrade, as explained in K16103: Extending disk space on BIG-IQ Virtual Edition.
    Important: Upgrading a node requires at least two volumes, so be sure you can extend the /var file system on both volumes to the same size; otherwise, upgrades might fail.
Even though you can log in to the BIG-IQ system after the software is installed, the system continues running background database re-indexing processes. For large configurations, re-indexing can take up to an hour. If you perform any searches on objects before re-indexing is complete, BIG-IQ might not return the expected results. During this time, you can continue with the rest of the upgrade process.
