Again this is not a TSM solution, but we use an EMC product to duplicate disks. 
 As long as both disks are available to the system at the same time take a look 
at OpenMigrater if you have access to EMC software.  It does a block level copy 
while the system is up.  When it is done it keeps the drives synced until a 
reboot replaces the old drive with the new one.  We usually see about 20-30GB 
an hour.  We have done 10 million + file systems in just a few hours.

Well, it turns out that the client has no downtime for this system so I
don't think the image thing is an option. Not to mention one of the admins
installed the LVSA code through the GUI setup wizard the night before and
chose to reboot later and the system crashed with a bugcheck for
TSMLVSA.sys yesterday. IBM had multiple tickets where this had occurred at
other customers in their database. We are waiting on a reasonable
explanation from IBM but the client is not too comfortable with the image
idea at this point and is looking to use their old Backup Exec system where
they have been successful doing this in the past (SHAME! SHAME!). I
suggested the robocopy method to them but it is their decision/data.

Thanks for all of your help!! Your are a great bunch of folks!!

If you assume a file create rate of about 100,000/hour then you are looking
at a 20 hour restore if all else goes well.  You might squeeze more file
creates out of your new server, but who really knows?  If you assume a 200
GB/hour transfer rate and use image instead, you can cut the restore time
in half. You can't improve the file create rate by using multiple streams.
In fact, that actually reduces the rate.

I'm still advocating the image route.

It is ~2,000,000 individual files after hours.
