You can move it now, or in the spring. I have done it in the spring. If you wait until spring, I think you would want to move it before it gets too much growth - and I would say if you can move it before it breaks dormancy if possible.  If it has broken dormancy in the spring, I think you will be fine. If it has a fair amount of growth, I think it would set it back.  If needed, maybe mark it now, so you know where the plants are in the spring, so you know where to dig if you want to try to move it when it is dormant yet.
