We are planning on upgrading our zone from 10.3.3 to 11.2.2 in the next few weeks. Management is asking us to test what the impact of all ZCM services down at the same time would cause. Has anybody experienced issues with workstation login during their upgrade? I'm struggling with what value it would be to stop services on both primaries and then test logging in. In my mind, this should not stop workstations from logging in, just no availability to install software from the Zen window. Any experiences would be great.
