Yes. You are right but still, suggest you go with offline configuration.

 

  1. Open proactive request with the f5 vendor
  2. Verify console connectivity
  3. Backup existing configuration
  4. On activity day, start upgrade process with standby
  5. Relicense standby device
  6. Upgrade the device to a new version
  7. Boot with new volume/version
  8. Failover the traffic from active to newly upgraded device
  9. Verify the connectivity and compare pre and post-upgrade configuration
  10. Do similar steps (5 to 9) for another device

    I had a doubt on step 8 - Let me drop my queries in very clear way. Please reply question wise.

     

    1. Do I need to perform Force Offline before following steps - 5 to 7 ?
    2. Do I need to do Release Offline before upgrade or post upgrade ?
    3. Will it come as Standby as it was earlier before the upgrade ?

    After I ensure the traffic flow and in-out packets, I should follows the below steps -

     

    1. Do I need to Force Standby the Active ?
    2. Do I need to make Active as Force Offline ?
    3. Do I need to follow the same upgrade steps like what I did for Standby ?
    4. Now Active comes up as Active ?
    5. Do I need to do sync ?
