Put a webpage up in the old space, with the text "please wait while we redirect you" or something similar.
In the <head> section of that page's html add
<meta http-equiv="REFRESH" content="0;url=click here">
the number in front of the url, in this case '0' sets the amount of seconds before it redirects. If you are putting text or images on your page, I suggest you set that a bit higher.
