If you mean by cloning, to make an exact copy, then Norton Ghost works wonderfully. I'm using 2003 and it works great. Clone to another hard disk or an image to CD(s). You can also clone a smaller hard disk to a larger hard disk, Norton takes care of the partition sizes automatically. I have used it on sme 5.5 & 5.6 quite successfully to move to a larger hard disk.
