Q.platycodon grandifloras balloon flower
I must move this plant to a new location. I see that it is best left undisturbed, however. What tips can you give me to move this plant? How deep is the root system? If I dig deep enough and wide enough, will the move be successful?

Balloon Flowers have a long tap root, they will not do well in transplant.
For the best chance for success, move your plant in early spring.
Dig down as deeply as you can without disturbing the tap root and leave all the soil intact.
Move the plant to its new location right away.
