Most Portlets offer an Export utility, which lets you export an object or list of objects to a file. To export an object, select it (from within the appropriate manager) and right-click, then select Export. The export goes to the browser’s default download location.
You can use exported files as seed files, letting you modify the application for later installations. You can also import these files in client applications running on other servers. Finally, the export function provides you with a convenient backup mechanism.
