Since no one has answered, I'll take a stab at this one: just like moving any other large plant. They are ubiquitous landscaping plants in my climate and readily available in flats, one, and five-gallon sizes at all nurseries and big boxes, so I've never moved one. However, I would wait until the best time of year for transplanting (Jan-Feb here, probably a little later where you are), dig as big a root ball as I could manage, slide a tarp under it and with the help of some hearty person lift it out, etc. I don't imagine it will require much in the way of special care.
