Traffic group between minor 11.x versions

I'm going to try an upgrade from 11.2 to 11.5 on a couple of BIG-IP 6900 in active/standby.   Does anyone know if the traffic group would keep working between the two different version?   In th...

    Correct. I'll be upgrading our production LTMs next week in almost the same fashion, except we're going from v11.2.0 to v11.4.1. We also have 6900s in an active/standby pair.

     

    Every time we've upgraded our LTMs in the past (10.2.1 to 10.2.3, 10.2.3 to 10.2.4, 10.2.4 to 11.1.0, 11.1.0 to 11.2.0), we've done it in this fashion. Never had an issue.

     

    Ensure your configurations are synchronized between the two units before you start and you should be fine. Oh, and be sure to re-license both units before initiating the new code installations so you don't encounter licensing issues after booting into v11.5.

Hi Cory,

 

you know, we will perform the above upgrade on a production network, That's why I wanna make sure I understood you fully.

 

  1. We have two big-ip 6900 in active/standby, both devices are equipped with sw 11.2.
  2. We will upgrade the standby one to 11.5
  3. We will force the failover so that the 11.5 will take over as active.
  4. We will upgrade the remaining device, now in standby, to 11.5.

Would that work? without split-brain scenario?

 

Thanks again
