Replacing / cloning My World Book Live HDD

Hi i have the 2TB my world book live HDD, does anyone know how I can replace / clone the drive for a 4TB one?

You may have a My Book World or a My Book Live, but no both in one :smileyvery-happy:

No need to clone, also it may be hard to do, or not possible, depending on the dives models.  The easiest to do is transfer the data manually over the network, without using any software.
