moving old grape vines
We live in my husband's grandmother's house and the grape arbor is falling down, so we're intending to pull it out. The grapes are planted in a location with poor sun, so I'd like to move the plants. The problem is that they are very old, probably older than 60 years old, and were planted by my husband's great-grandfather. Understandably, he'd like to keep the same physical plants. I'm not real sure it's possible though.
1. If it were you, would you attempt to move the plants?
2. If I were to instead root a section of vine, what would be the best way to go about it?
3. The place with the best sun is along a chain-link fence. Would this be a good place to anchor the vines or is it better to build an arbor?
Thanks for any help you can give me!
