Mark:
To import an existing web project onto a new server, you can do the following:
* Export your web forms as an ACP
* Import your web forms ACP into your target server's Data Dictionary
* Create your web project, and associate your imported web forms
* Bulk import your content
As you note, your XML will not automatically be associated with your imported XML. If you click EDIT on the XML, however, you'll note the last sentence where it prompts you to associate the XML with one of the web forms associated with your project. Click on the hyperlink, and select the relevant web form. You will be able to edit your content, and you will re-generated your assets. You'll be able from then on to edit that XML or its generated assets using that web form.
Unfortunately, this is a manually, asset-by-asset, user-initiated association. Over time, everything will get reassociated.
We have a filed improvement request to rip through all XML to associate. That, however, is not currently scheduled for a release.
Hope that helps a bit!
