I don't know 'Crepuscule's reputation as being difficult to move, but I moved mine twice in its early years and it didn't seem bothered about it. In my climate I would transplant a rose or shrub in mid- or late autumn, once the heat was gone and the plant had gone dormant, or as dormant as it would be likely to be, but before snow, frozen ground, and other unpleasantnesses of winter. I try to plant everything before Christmas, to give the plants the winter to get established before drought the following summer. However, your colder climate and different kind of summer may require a different planting schedule, and I'd like to hear what other zone 5 or 6 gardeners have to say on the subject: would shifting 'Crepuscule' in fall render it particularly susceptible to freezing to death in winter?

Zones 6 to 7. Excuse me.

yep, in agreement with Melissa - to get them up and moved while there is still warmth in the ground but before the winter sets in hard. I am also thinking that you could lose a LOT of the top growth and encourage more basal growth next year - there are a number of ways to do that, so don't be hesitant about cutting it back hard. Mine has always grown with many small canes from the start, looking rather more like a multiflora rambler than a climber, so I think it is in the plants DNA to respond very differently to climate and position. I see no reason why yours should not grow away once it gets its roots into the soil. All the normal rules apply - keeping the rootball as big and undisturbed as possible, having a new hole ready, lots of water and so on.
