Export/Import VM Folder Structure to new vCenter

Afternoon,

We are building a new vCenter 5.1 Environment.  Want to duplicate the VM Folder structure from the 4.1 vCenter (Folders under INVENTORY>VMs and TEMPLATES).  All we need are the folders and Sub Folder Structure.

VCENTER >

     DATACENTER>

               PARENT FOLDER 1>

                    SUB FOLDER 1>

                    SUB FOLDER 2>

               PARENT FOLDER 2>

                    SUB FOLDER 1>

                    SUB FOLDER 2>

Etc etc...

How would it be the best aproach to do this with PowerCLI?

I have seen a few other posts on this topic, most involved a VM Audit, which is not what we need.  Just the complete Folder Structure of a 4.1 vCenter (including all sub folders).  Nothing Else.

Goals:

1. Export the full list to file (assuming its a CSV file).
2. Import the list from the file to the new 5.1 vCenter.

Thanks,

BostonTechGuy.
