BigIP TMOS upgrades through BigIQ

Hi,

I always create two rollout from Big-IQ. I run a script that tells which are standby. Roll out upgrades to that group. Once done, failover to active, monitor, then run all formerly active (now standby) devices. Big-IQ will reboot all of your devices at one time if you put them in one group. Trust me, it is quick, nerve-wracking, but not efficient as you will take down time unless you manually divide and conquer. It is more work than originally hoped for but less than performing manual upgrades. Hope this helps!
