Answer: It should survive, but it will probably drop some of its leaves if you move it in mid-summer. Water it thoroughly the evening before you plant to move it and then dig the new hole before you unearth the plant. Make the move as quickly as possible so the roots are not exposed to dry air and sunshine for any longer than necessary. I'd move it when the air temperature is the coolest and it will suffer less during the move. After replanting, be sure to water well to help settle the soil. Hosta's grow best in shade, so be sure it has a shady new home.
Best wishes with your garden!
