I would definitely check with the MFG of the shed and see what they recommend. If that is a Tuff Shed, then they have the equipment to move them whole or in pieces.
Here in Louisville, I was looking at some sheds and was given the option of having it built on site or delivered already built and then placed on the site. As I don't have a driveway they would have to bring it in in pieces and build it on site.
However, if you have a saws-all it wouldn't be that hard to slice and dice the parts of the shed to disassemble it and move it and then piece it back together. Those sheds are usually pre-fabricated in panels at the factory and then the crew delivers it, and either nails or screws the pieces together. Even if you can't reassemble it to it's original shape, just the materials alone would be worth it
