Welcome to the Q&A Forum

Hi Newbie SEO here.... I converted quite a massive site to wordpress (www.yourbusinesschannel.com). For a number of reasons, over 1000 pages were not converted and the URLs could not easily be preserved in any event I am now going to add these pages back by importing a large CSV into wordpress. However what is the best way to tell google that the pages are now back and at new addresses? Is it to submit a site map and get the site recrawled from scratch?
