I would suggest TotalComander it is freeware and will move entire File Tree's from one location to another (whilst maintaining permissions/structure etc) and then the renaming you may have to do manually at the other end? I'm sure you have your reasons for wanting to rename a thousand directories ... but this is by far the easiest way to move the file structure!
