we are using at the moment the 11.2 appliance and we are planing to update/migrate to the 11.3 appliance.
I found the ZENworks 11 SP3 Ugprade Guide and the most questions are solved.

There is just one question. We did some custom modifications, for example - we add a permanent mount to the image folder because this folder is moved to another server.
Are these settings are migrate too or only things like network settings like ip adress, dns name, zcc settings, database and so on?
