Someone in another group I read wants to move some 100 year old
grape vines . Any chance of success ? My understanding is that
they root very deeply , wondered if that would make it difficult

depends upon what type of vines. if they are grafted
upon different root stock, etc.

how many vines?

if they are self-rooted (all the same plant with no
graft) then they would be much better off by taking
cuttings from 1yr wood and rooting those (similar to
how you'd do roses or many other woody stemmed plants).

I don' know ... were they grafting grape vines on hardy rootstock a
hundred years ago?

yes, the bug that eats roots affects european varieties
that haven't been hybridized to defeat them...

Phylloxera -a root-sucking aphid from America introduced into Europe
on the roots of North American vines a couple hundred years ago.
