So... does this mean there's no need to enable this update task if we're running ePO 4.5, upgraded from 4.0. As I understand the guide's extract, ePO 4.5 migrates the server key thus there should be no need for this update task, right?
I'm going to go with "if it ain't broken, don't touch it" approach, but would still like to understand as many of the features as possible.
Ideally, you would want to keep the Key Updater enabled. This will run if there is a change in the keys (e.g you promote a new master key). If you disable this component, the agents will not be able to stay up-to-date with the latest keys.
