Sue, I'm digging lots of my daylilies and moving them. I'm leaving all the dirt that I can on them, and digging deep enough so that the roots are disturbed very little, if any. Why would mine be wilting, if the cause would be because there isn't enough root left? Most of mine have had all of the root left, and I'm still getting wilt. 
I would say it's pretty much impossible to get all the roots, including fine roots which are easily damaged - daylily roots spread quite a bit although you have a better chance if the soil is very friable. Watering well several hours or a day before moving them may mitigate wilting somewhat but I can't think of another reason why leaves would wilt on being moved if the plants weren't somehow short of water when dug or weren't wilting before. A long shot might be if a largish amount of fertilizer was added to the planting hole (which can draw water out of the roots).
