Point out that OCIM App Servers aren't modified once deployed
I was working with a task that involved specifying the package's version. I ended up not knowing that the app servers shouldn't be modified when deployed, I went ahead and modified the app server instead of changing the settings for the OCIM instance.
It is important to state in the documentation or the onboarding course that OCIM instances should be modified by changing the Settings for it, such that new app servers with the new settings are deployed instead of modifying the existing ones.
