Question
What is the best way to move a Joseph's coat bush rose, and what are the requirements (sunlight, drainage, etc.) of the spot it is moved to? The closest city to me is Savannah GA

Answer
In your area you don't get any nasty weather which usually puts roses into a period of dormancy and this is always the best time to move them. However moving a rose in your zone is done under different conditions and so the rules are not the same as other zones. First have the new hole ready before moving the rose. Although roses like full sun, Josephs Coat has a tendency to fade in full hot sunshine and the flowers blow quickly. To counter this habit, place him in an area that gets mainly the morning sun or late afternoon. All you really need is 6 hours of full sun. You will then see that the colours stay more vibrant and the flowers will be a more attractive shape.
The night before you move, cut back Josephs Coat to about 3 feet and cut out any dead canes of those that are thinner than a pencil and water him well. You can't help damaging the root system when you dig the rose out and pruning him back means the roots don't have as much growth to cope with. Plant him right away firming the soil around him with your feet, place some sort of mulch around the base to keep the new roots that grow cool as well as the older ones and then water, water, water. Never mind if he looks droopy, just ignore the fact he is in a snit and keep watering. If the sun gets too hot and makes him droop, then throw wet material over the top of him. The reason that transplanted roses die is because digging them out has damaged or even killed the feeder roots which do the job of taking up the nutrients and water to the rose canes. Now you have to do the job for at least a couple of months until the new ones have grown and can do the job as before. Sometime roses when they have been transplanted in warm gardens may not perk up until the middle of the summer. Hope this helps.
