Exporting Release

If you want to move a complete configuration from a test to a production server by using the portal Release Builder tool then you should use ExportRelease.xml.

<request xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:noNamespaceSchemaLocation="PortalConfig_1.4.xsd" type="export"
 domain="rel">
 <portal action="export" />
</request>

As you can notice request has domain='rel' attribute which indicates that only shared resources(From release domain) should be exported. Private resources are in customization domain they wont get exported
