The only practical way to do this is via replication. I believe there
are some products out there for Windows and Linux that are software
based. Just set it up, wait for it to finish. Verify it is fully
synched and cut over to the new replica.

Amen to Dwight's comment! And can you imagine a filespace with 10M
files? I shudder...

I've seen restores of 1+M files take days due to the delays associated
with
general system over head (creating directory entries, etc...) and by
days I
mean 5-7+.
And so again, I'll mention...
Just because you CAN put a million or more files on a single drive
doesn't
mean it's a good idea!

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.
