I think you could definitely heel in your roses over winter at your new home. I included a link for a few ways to hold on to bare root roses, which is kind of what they will be when you dig them up for transport.

I would cut the canes down to 1-2 feet to make them easier to handle and you can lay them in a trench...make sure you cover them with plenty of mulch and plant as soon as the ground is workable in the spring so that new tender roots aren't damaged when they are moved. Watch for heaving during the winter to make sure the roots stay covered with soil or mulch.

Another option would be to trim the canes and pot up these roses in nursery containers and overwinter in a sheltered area outside (covered with a pile of leaves/straw mulch), in an unheated garage or basement, or even put the pots in a trench and cover with soil and mulch until spring.

If you do pot up and overwinter indoors, I've used a black garbage bag over small potted rose starts to help keep light from triggering weak foliage growth...make sure you cut a generous ventilation hole in the top.

If they are healthy, established roses, they should survive the transition fine :)
