Protecting Mobile PAC Changes
Mobile PAC server software includes a Custom folder where you can preserve most customizations from being overwritten at upgrade. You should back up the Custom folder as a precaution, but you will not have to recreate your changes for each upgrade.
In general, the folder structure in the Custom folder mirrors the Mobile PAC folder structure. The Mobile PAC application checks for the existence of specific files in the Custom folder to be used as overrides for the default versions of those files. The illustration shows the Custom folder structure as delivered with Mobile PAC.
