We have a custom logon page that is more than just a replacement of the image and modifying of logon screen text. The problem is the former developer of it didn't leave in the much of the way of documentation.
Is there a clean way of migrating this page, by exporting the necessary files out of portal A, and importing/copying them to portal B? We don't need to do any further modifications to the content, but just simply move it over to a different portal. Our version is NW 7.31 SP9.
