and why should you redirect??
and what do you mean with “Because the google-indexed pages will no longer be there”??
The website is written in basic HTML.. say a page is indexed in google as xxhttp://www.website.com/articles/anarticle.htmlxx, wouldn’t I need to redirect it if I want to change the website’s structure and use WordPress or just plain and simple rebuild it in php? Without a redirect, won’t I need to keep the exact same filetree?
