Here is the LAN-ACES solution.

To create a new level at the destination user, you would to do the following at the server:
1. Download the 'prepend' utility from our website at http://www.lan-aces.com/download/prepend.exe and save it into the LOGIC directory at the server
2. Open a command prompt and go to where you put the folders. Such as:
D:
CD LOGICuserSMTPJOHN
3. Run the prepend utility to add the new level (note the period at the end of the folder name):
LOGICPREPEND JOHN.
4. Move all of the (newly renamed) folders to the previous level, for example:
source: LOGICuserSMTPJOHN
dest: LOGICuserSMTP

IN the above example substitute INTER for LOGICUSERS for USER, kraig.frymier for user and kevin.paterno for JOHN.
