will my grapes survive ?

My brother just dug out 6 huge old grape vines. Theres a bout 45cm tap toot and quite a few laterals.
What do we think their survival rates are for replanting ? The pots are pretty big so they'll need some big holes.
If we think they will survive , any tips for helping with transplant shock?

Cheers

I can’t predict if your grapes will survive, but grapes are tough plants.  Occasionally they can become weeds.  Cross your fingers and hope for the best, they just might make it.  Personally I would get some sort of rooting solution on them and generally baby them.  Just my 2 cents.

Well done, not an easy feat taking out a grape, let alone 6. I agree with Eric grapes are strong plants they'll probably make it.
I've done one, it didn't have a lot of roots, same as yours, but it didn't have the long stems. It started from scratch. I was there to water it regularly the first year. Second year it exploded, grapes and all. But small grapes. I removed it last year. Maybe i did cut the above ground part below the graft. Don't make that mistake.
But if you leave too much branch/foliage and it's a long way for the roots to push the water into the leaves it will cost a lot of energy.
Ideally find where it's grafted on and leave a short bit above it, enough for two or three buds to appear.
Then it will not be a far push for the rootsystem and it can start slowly, build up it's rootsystem and then pace itself. Mine grew two and a half meter first year from a sleeping bud. So then you can still have a good growth.
But that's if you find the grafting place...
