LTM Upgrade Process

I am planning an upgrade from 11.1 to 11.3. The documentation I've been able to find looks specific to upgrading 10.x to 11.x (http://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/bigip-upgrade-active-standby-11-3-0.html). Should I use this same document as a guideline for upgrading? Also, for an Active/Standby configuration does it make sense to upgrade one side, let it run in production for a day or so, then finish the other side? Also, is there a back out process if there are issue?

    Since you're already at 11.1, you should just install 11.3 to a separate volume and reboot into that volume. By default your current configuration should follow the installation. If you've been on this build for awhile, make sure to renew your license before upgrading. The back out process would involve booting back into the 11.1 volume.

    Always a good idea in my opinion.

    The HA heartbeat is the same. I would turn off connection mirroring.

    Upgrading firmware will also mean to upgrade the build-in FPGAs and the AOM.

    That´s why there is no 100% roll back in my opinion.

    But of course you can reboot into the previous volume at any time.

    In case you face an unwanted active / active you can force a device in offline state (WebUI device settings) or via tmsh: 

    tmsh run sys failover offline

    To recover: 

    tmsh run sys failover online

    I´m wondering why to get onto 11.3 instead of moving on to v11.4HF3? Personally today I still prefer 11.2.1 w/ latest hotfix if there is no need for one of the new modules i.e. AFM.
