That's a lovely looking plant, really nice deep purple flowers, not seen it before. I've moved shrubs and large plants before in perhaps less than ideal circumstances.
It's still really mild and the ground is warm so I would go for it, cutting it back and take as much as the root ball as you can and water it in well.
The cuttings as suggested would then give you an insurance policy if it didn't like it.
