Vcmp hosts and Guests upgradation

Looks good...Make sure you activate/re renew your license before the upgrades on vCMP hosts again. This will stamp the updated Service check date. What are you shutting down? I am not clear on that. You don't have to shut anything down. So to min the impact leave the active devices on lest say host 1 now your host 2 will have the 2 stby devices. Put the stby devices in offline mode and upgrade - reboot into the new partition. Offline to Stby...and do the same over on other host...make sure that newly upgraded devices are active and are getting traffic before you start working on the other devices. I followed the same plan...looks good. Oh open a proactive Sev-4 ticket with F5 just in case you have any issues. Upload Pre upgrade UCS to iHealth.
