Site migration with "New blog templates" ?

Hi,

I am looking for the simplest way to "clone" a site, I need to set up a similar one on another Domain.
So the best thing would be if I can just take my site and install it on another domain.

So I will go an try to do this today...
Could anyone tell me if the "Snapshop" plugin or the "New blog template" plugin work better for this?
