Exporting Task Folder

Hi, I have a couples of Task Folders (wm_xt_fabricfolder) under Folders>My webMethods Applications>Fabric Tasks.
My folders contains custom portlet, wm portlet, another task folder or frame.
What is the best way to export them for a future installation on another WM server. Right now I’m using Content Import/Export tool but this tool permits to export only one Task Folder at time. And when I importing the export file on another server sometime is not working and I think its because a duplicate tempalias in the export file.
