The tree is a white Chinese Fringe tree (Chionanthus virginica
). I have read that large specimens such as yours can be transplanted, but the survival rate is just slightly over 50%. I think I would hire professional arborists to move the tree. Otherwise, just get a smaller one to plant in your yard.
