How to upgrade an HA pair of F5 LTM appliances.


  1. Sync the config between the two appliances if needed.
  2. If running ASM, sync the policies.
  3. If running APM, sync the policies.
  4. Download the Base image and the latest hotfix.
  5. Import the base image and the hotfix into both the active and standby appliance.
  6. Reactivate the license on both appliances.
  7. Generate a new UCS archive of each appliance and save them off of the box.
  8. Perform the install into a clean partition on both appliances.
    1. The install is behind the scenes and does not interrupt traffic therefor this can be done on both the active and standby.
    2. If you launch the install from the hotfix it will install both the base image and the hotfix together at the same time saving a step of installing the base image and then the hotfix.
  9. Reboot the standby unit (Unit 2) to the newly upgraded volume.
  10. Confirm the configuration has loaded and all pools and VIPS are green.
  11. Failover to Unit 2 and confirm this is passing traffic as expected.
  12. When Unit 2 is confirm to be good, reboot Unit 1 into the upgraded volume.
  13. Confirm the configuration has loaded and all pools and VIPS are green.
  14. Fail back over to Unit 1 and confirm this is passing traffic as expected.
