Copy and Export Your Web Site
If your web site is well constructed as part of the One Big Database, copying your site for archival or demonstration purposes can be very simple. Having your site exported to another web hoster using another software package has been nearly impossible. By adhering to good web architecture, your site should be able to be exported from one system to another and even keep your URLs intact.
One of the biggest benefits to adhering to the One Big Database theory, is that you can build a web site that can be copied easily and exported to another server with different software with pages and URLs intact.
