If you moved the vines last year they should be treated as newly planted vines so this would be their second year. It takes a while to get the roots to regrow enough to support the vines and crop. Prune them back depending on how big the vines were when moved and don't try to take a crop or at least not much yet. It is too soon. If you post a picture of the vine now and maybe before the move we can help tell you how to prune it this year.
