Converting from v1.1 to v2 and problems with switching design mode

However when opening the web page and trying to switch to design mode
there are a number of error messages appearing. Such as can not nest
TD within a Table, non matching tags, nesting tables within a form and
some properties no longer available.

What is the best method of converting the web pages so that there
design is available in VS 2005?
