Convert Straight HTML Site to ASPX

The site is [[login to view URL]][1]? I would like: 1)? Convert all pages to aspx files 2) Update the links on all the pages to reference the new aspx files 3) Any broken links be found and fixed 4) All pages be standards compliant (you tell me what checkers you will use, ie. [login to view URL],? <[login to view URL]>, etc..) 5) Style sheets be used 6) Viewable on IE 7, 8, Safari, Mozilla The questions I have are: 1) If javascript is used? should that? be replaced with activex or something or? is this OK? 2) What about broken? search engine links if? we rename all these files?? Is there something we can do about this or just wait till the search engines? refresh? 3) Should we be compatiable with any more or less browsers? 4) Is there anything? else we should consider when doing this? 5) Can you think of some good reasons why would we want to do this?
