I Live in Zone 7 and Want to Know if My Russian Sage Plant Survive as I Just Transplanted It This December.
You are asking because you know it is an iffy situation. December is fine for planting spring bulbs but awfully late to allow a transplant the time it needs to get roots established. Even in winter, the roots must take up water or dry out and die. Two suggestions: cut it down to 6-12 inches now and water the ground when it gets dry, even in winter.
