moving a cherry blossom

Hi all,  I've recently moved into a house with a lovely cherry blossom in the garden.  Problem is, it's in totally the wrong place and I would like to move it.  I'd guess it's been in the ground about 7 years, so it's not huge, but it's no longer a sapling.  I'm assuming it would be best to move it in winter, but does anyone else have any advice about the best way to move it? 
Thanks.
