title: How to do a htaccess modrewrite for redirecting a url?
body: <p>Got an urgent issue, and I'm totally stumped.</p>
  
  <p>We recently migrated a bunch of networked blogs, and realized one of them was using a subfolder structure, whereas all the new system is all subdomains. The wordpress multisite system doesn't allow for both subdomains and subfolder structures, so I'm guessing the logical solution would be to use htaccess to redirect requests for the old urls to the new url. But how do I write the code in the htaccess?</p>
  
  <p>I need to make all requests to <a href="http://www.mysite.com/720/etcetc" rel="nofollow">http://www.mysite.com/720/etcetc</a> 
  to <a href="http://blog.mysite.com/etcetc" rel="nofollow">http://blog.mysite.com/etcetc</a></p>
  
  <p>Is this possible or is there another more viable solution? </p>
  
  <p>Your assistance would be greatly greatly appreciated.</p>
  
  <p>Thanks in advance.</p>
