You shouldn't have any problem as long as you can still read
the old disk and the new one is the same size.  Just don't
try to boot with both drives still in place after the copy
because you will have duplicate disk labels.  Those used
to confuse the kernel when booting, but perhaps it has been
fixed by now.
