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. For more information related to a specific Big-IP release, there are additional details in the release notes for each version. For more information, refer to the Release Notes page.
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
vCMP Big-IP Guest instances
For information regarding upgrading from Big-IP 9.x to 10.x, refer to the following guide: Manual Chapter: Upgrading from Versions 93x and 94x.
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.
Generate a qkview diagnostics file and review iHealth for any triggered upgrade-related heuristics in the Diagnostics and Upgrade Advisor tabs. Each Big-IP product has its own set of requirements pertaining to software upgrades and iHealth is the best utility to find up to date heuristics governing successful Big-IP product migrations.
Create a UCS archive of the Big-IP's configuration and save it remotely in case it is needed for recovery purposes. For more information, refer to K4423: Overview of UCS archives.
Verify your Big-IP system is running version 10.x, 11.x, 12.x or 13.x and is using the volumes formatting scheme (the command lvscan should not be blank).
The command output should appear similar to the following example (the sizes may differ):
ACTIVE '/dev/vg-db-sda/dat.share.1' [30.00 GB] normal ACTIVE '/dev/vg-db-sda/dat.log.1' [7.00 GB] normal ACTIVE '/dev/vg-db-sda/set.1.root' [256.00 MB] normal ACTIVE '/dev/vg-db-sda/set.1._usr' [1.34 GB] normal
Check running configuration integrity by running one of the following commands. No errors should be returned (warnings may not hinder a software upgrade but should be corrected if possible).
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.
Features: - Inexpensive compared to higher throughput Big-IP VE licenses. - LTM, GTM, DNS, AFM, ASM, AAM, CGN, APM Lite (10 users). - In Big-IP v11.4.1 - 11.6.x, you can import Big-IP 10.x - 11.x UCS archives. In Big-IP v12.x, you can import Big-IP 11.x - 12.x UCS archives. Copy the UCS file to /var/tmp and use the following command:
tmsh load sys ucs /var/tmp/
.ucs no-license no-platform-check
Limitations: - May not be available in all countries - Total system throughput limited to 10Mbps
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:
