You can likely successfully transplant the shrub in fall or early spring.
Either time, prune 1/3 of the plant prior to digging up, to lesson the stress.
Dig as much of the root ball as possible and plant the shrub at the same level in the ground.
Make sure you apply plenty of water in the first 2 weeks. Adding 2 to 3 inches of hardwood mulch will help with moisture retention.
