Outlook 2007 PST Redirection/Scripted Move to SAN

Hello,

I would like some feedback to the an effort I have been directed to
complete. I currently have 2500+ outlook users with their PSTs on their
local systems. We have made a sizable investment in storage 400TB. Storage
capacity is not the issue.

I need to be able to perform the two actions below either via script or via
GPO.

1) Physically relocate every user's PST file to the SAN.
2) Re-map the user's PST file to the new location.

Both of the above tasks need to be accomplished without directly touching
every system, as this task would require emmence manpower and an almost
unlimited amout of time to accomplish.

Does anyonw know how to accomplish this task? I am being pressured by my
superior to accomplish, but as of now have not found an automated solution to
accomplish.

I greatly appreciate your time and efforts in review and proposing solutions.
