The information is this series is meant to help a Big-IP administrator complete a software upgrade. I have assisted with hundreds of Big-IP upgrades and hope to help you complete the task as smoothly as possible.

The information in this series applies to:

  • F5 platforms which support Big-IP version 10.x - 13.x
  • Big-IP Virtual Edition
  • vCMP Big-IP Host platforms

Note: If you are familiar with Big-IP upgrade behavior and only need to review the actual steps, use the Performing the Software Installation section. To review Big-IP upgrade behavior in more detail, please review the other Parts.

Recommendations Prior to Installation

  • From the F5 BIG-IP TMOS: Operations Guide; before you upgrade the BIG-IP software, review the release notes on AskF5 (support.f5.com) in the Documentation section for your product and version. Pay close attention to the following items:
    • Review the Known issues list.
    • Review the Behavior change section(s).
    • Review the Upgrading from earlier versions section.
    • Review the Upgrading from earlier configurations section.
    • Review the installation checklist.
  • Verify a connection to the serial console port is working. This not required but will allow monitoring of installation progress and provides additional recovery options. For more information, refer to K7683: Connecting a serial terminal to a BIG-IP system.
  • When you have a date for the upgrade, we recommend starting a proactive Service Request with your plan in case there are complications during your change window. For more information, refer to K16022: Opening a proactive service request with F5 Technical Support.
  • Testing the upgrade procedure on a lab environment using Big-IP Virtual Edition can be helpful to find potential issues before they are encountered in a production environment.

  • Retain a UCS archive from every Big-IP in your network on a remote filestore to aid disaster recovery. Even if the archive has aged and does not contain all configuration objects, it will provide faster recovery time than completely reconfiguring the Big-IP. For more information, refer to:
  • For full planning and assistance during an upgrade, F5 Professional Services is a good resource. Support will answer specific questions regarding the upgrade but can't be used start to finish to perform upgrades. For more information, refer to:
