I need to remove an old postnuke installation that keeps getting hacked into that resides in a folder called "articlebase". I plan on installing the newest version of Wordpress to display the articles in a different folder. Is there a way I can let Google know that the "articlebase" folder is under maintenance (while it appears broken)? I want to remove the Postnuke software asap, but have too many internal links pointing to the articles.
After the Wordpress installation is updated with all the articles, I plan and doing a 301 redirect from the old postnuke site page to the Wordpress version of the page.
