I used the Copy function to create a copy of my whole site, with the "Relate copied items to original" option checked.

It got half way and the site died for an unrelated reason. I noticed that half of the pages had been copied, so I deleted those pages.

I tried again.

This time the copy succeeded, but half of my pages are still related to the old, deleted pages. How can I change the relationships so they are related to the new pages?
