Move Documents between Storage Areas

I'm trying to move particular types of documents, mp4's, to a new storage area so that we can manage the files a little easier.  Here is what I have done thus far to accomplish the task:

  • I set up a saved search in PW Explorer that finds all mp4's in the datasource that are on a particular storage area
  • In PWPS I am using Get-PWDocumentsBySearch to retrieve the documents and assign them to a variable called $docs

I was hoping to use the cmdlet Update-PWStorageAreaProperties to change the storage area for the documents but I am unclear of how the syntax should be.  Based upon the help file, the cmdlet sounds like it might not work for what i'm trying to do?
