Thanks, moshu…
For every current page, the URls are structured like this…
/news/123456/contentname_feature.php
The new structure would be similar to…
/news/contentname-feature-in-new-wordpress.php
They’re not too far off in structure, so I guess I’m wonder if I’d be taking all of the content from the existing pages, transferring them into new WP pages, keep the current/old pages on the server and use .htaccess 301 redirects? I’m worried how that would affect our ranking/placement in Google… I can’t see it being a duplicate content issue since both urls would be pointing to one piece of content.
