Preparing to Upgrade a BIG-IQ version 5.2 or 5.3 with a Data Collection Device Cluster

Downloading a software image from F5 Networks is the first step to making it available to install on the BIG-IQ system.

Important:

The BIG-IQ disk space compatibility check is not supported for BIG-IQ hotfix images. To avoid errors, download a standard BIG-IQ .iso image.

  1. Log in to the F5 Downloads site, downloads.f5.com.

  2. Click the Find a Download button.

  3. Click the name of the product line.

  4. Click the product name, Centralized Management.

  5. Click the version number you want to download.

  6. Read the End User Software License agreement and click the I Accept button if you agree with the terms.

  7. Click the BIG-IQ version <version number>``.iso file name that you want to download.

  8. Click the name of the closest geographical location to you.

    The software image downloads to your local system.

The software image is now available for you to upload to BIG-IQ to make it available for this upgrade.

Before you can upload a software image to BIG-IQ, you must download it from the F5 Downloads site downloads.f5.com.

You upload the latest BIG-IQ version of the software image to the BIG-IQ system to make it available for this upgrade.

Important: To make sure the software image successfully uploads, don’t log out of BIG-IQ or close the browser window until the software image name appears in the Available Images list.

  1. At the top of the screen, click System.

  2. On the left, expand THIS DEVICE > Software Management, then click Available Images.

    The Available Images screen lists the software image files that are available for install on this BIG-IQ.

  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 BIG-IQ uploads the software, it verifies the image. This verification process can take several minutes. When BIG-IQ is finished uploading and verifying the image, the software image displays as Verified and is available for installation on a device.
