Any time from now on - but only if the ground is not frozen, nor waterlogged, and you're able to dig it properly to create a new planting area - the roots will be pretty widespread and deep, so dig out carefully, starting a foot to eighteen inches away from the central trunk, breaking as few roots as possible, and keeping a good rootball.

Done carefully, hopefully it will survive. Remember to water it well in its new position - if it starts to look droopy and not well, reduce the topgrowth by a third to a half.
