uld follow when moving any plant from one location to another.
1. Identify the plant to be moved.
2. Choose a new spot for your plant.  Be sure you have thought about the mature size of the plant and plan accordingly.
3. Dig the hole in the new spot. I usually estimate the size of the root ball and then dig a shallow hole.  The reason I do this before digging the existing plant is I want to be sure that there are no obstacles like rocks, pipes etc in the spot I am choosing.  If you did the plant out of its existing home and then you can't dig a good hole in the new area you are stuck.  Amend the soil as necessary.  Be sure to not add too much fertilizer.  Do not fertilize in fall.
4. Dig out the existing plant.  Be sure to dig UNDER the roots as much as possible. I slowly go around the plant at a distance equal to the spread of the branches.  Eventually, you should be able to pop the plant out of the ground.  The slower you go, the more roots you are apt to get and the better the chances of survival are for your plant. 
5. Plant the plant in the new spot.  Be sure to pack the soil around the roots.  Take care not to damage the roots.  Do not do this step in the heat of the day. I like to do this in late afternoon so the plant can adjust overnight in cooler darker conditions.
6. Water your plant.  Stake it if necessary.
