how to replace old DW site with new WP site? [closed]

In practice there is no simple migration path from platform X to wordpress (or probably to any other platform). The reason is that usually no one moves between platforms without a very good reason, and when it happens there are usually also changes in the design to take advantage of the new platform, therefor you end up rewriting a a lot of the design. It doesn’t help that automatic tools (or recipes) usually produce hard to understand code.

The above refered to moving the design, content which is separated from the design is relatively easier to move, but with DW AFAIK content is mixed with design.
