Cloned my old hard drive

Now what do I do? I have a WD Passport Essential  External Hard Drive. Cloned my old hard drive into the passport essential by the way of Spotmau. My new Hard drive for my laptop will be arriving tomorrow [Thursday] and my questions is how do I transfer the data from the passport essential on to my new hard drive?

Thanks for the help

I’ve never heard of Spotmau.  You may have to go to them to make sure you did clone it, first of all, then to find out how to clone the new drive with it.
