1. See: post #6....determine the variety. Decide if it's worth the hernia to remove this tree?
2. IF its a good variety, and you can wait to dig it out, take a sharp spade and plunge it straight down around the perimeter of the root ball. For example, trace a root-ball, 18"-20" - (minimum) - out from the trunk of the tree, and sever/cut all the roots outside of this established zone. Wait for the tree to go dormant, then dig it out. Between the time of the root-severing and dormancy, the roots will try to regenerate, and will sprout some new feeder roots. Before digging out the tree, but after dormancy, I would also do a careful pruning, and establish a basic rack of branches...why lift extra wood? Without all the leaves, it will be easy to see unwanted branches, dead wood, etc. If the root system lives, the tree will recover from this pruning.
3. Move the tree to its new location and plant it into a prepared hole, and water it in. (Post #4)
You live in Zone-8a, so you have so extra time for the tree to establish itself in its new location. If you can wait for next Spring to move the tree, establish the root ball perimeter by severing/cutting the roots now, and leave the tree alone until it can be moved next season. It will be less stress on the tree.
Good luck.
