If you can mount both drives in the same box,

cp -a /oldraid /newdrive

should work.

If they're in separate boxes,

rsync -a /oldraid newmachine:/newdrive

should do the trick.

You should be able to use rsync if they are both on the same machine. May be
better if you stop the transfer for whatever reason. Its nice to also add
the -v (verbose) flag so you see it doing something. Such a larger transfer
may take a long time and if you don't have any output, it may look like its
not doing anything.

The problem with using "-v" is that you may miss error messages (amongst
the large amount of normal output). If you want to use "-v", then redirect
standard output to one file and optionallly, STDERR to another file.

You can always use strace to make sure somethings going
on. There's no need to slow the copy down with verbose
output.
