Hi there,
I'd like to update our IEM core from 2017.1SU1 to 2017.3 (in order to hopefully resolve a BSOD bug that's popping up on some machines who's agent has been updated from 9.6sp3 -> 2017.1SU1).
However, before I do this on the production core I'd like to test the update in a lab environment.
I have updated a test core now to 2017.3, I've rebuilt the agents and created a self contained exe agent and have installed this on a test workstation (hoping to install on another 3-4 for testing the BSOD doesn't occur).
As the UAT core contains a backup of the live database I've disabled the scheduler service so no tasks are run on production devices.
Question is, is there a recommended series of tests you can run through to verify most systems are functional, without affecting live devices? Does anyone else have a UAT testing procedure they use before updating IEM on their production core?
I can run tests such as software distribution to the handful of devices with the UAT agent, but I would have to enable the scheduler service for this wouldn't I....and that may potentially mean old tasks start running against devices, unless I clear every one out first perhaps.
