Hi Bill,

Sorry I've never used Nested Content so I have no idea how that works.

If you can get nested content as IContent nodes you can do this the same way I did using the API.

Edit: I just had a look at it. It's very similar to our homemade solution using the multinode tree pickers.

You should be able to do this using the following steps:

1. Grab the new root node for which you need to update the references.
2. Iterate over the tree and for each node:
   1. Get the full path
   2. Replace the ancestors with the appropriate new ancestors
   3. Save changes to node

I found this in the documentation so that should get you all the IContent nodes you need.

I iterated the content tree using a simple graph structure so that I didn't end up doing the same nodes over and over if they are referenced in many nodes. e.g

public class GraphNode<T>
{
    public GraphNode(T data)
    {
        Data = data;
        Visited = false;
    }
    public T Data { get; set; }

    public bool Visited { get; set; }

    public string Path { get; set; }
}
