Perhaps a rose expert can identify them, but I would guess it is extremely difficult to do so given the hundreds of different varieties and without more detail of their habit, such as are they bushes, climbers, multiflora or whatever, are they scented?
Transplanting them is technically possible but you should move them in the dormant period when they have no leaves. Trying to move them in summer would undoubtedly kill them, especially if they are large bushes.
If they are ancient well established roses they probably have a well developed root system that would need to be cut away to move them, so it may take some time to re-establish them if at all.
Don't forget you can take cuttings from them, of both ripe wood in the autumn, and even of softwood now, with care and misting.

I agree with Bertie, but as you say one way or the other you will be moving them then you have to take the. "nothing ventured" approach and give it a try!

To describe how to do it is quite involved so let me direct you to the link on my website that will explain what to do, then it's fingers crossed that it will work!
