Is there an advantage to the following commands:

<meta http-equiv="robots" name="robots" content="NOINDEX,FOLLOW">

vs.

<meta http-equiv="robots" name="robots" content="NOINDEX,NOFOLLOW">

The plan would be to view an existing obsolete highly ranked page, and allow it's links to be followed, with the future command to no index that obsolte page. A new page could then be created and indexed to replace it.

We have numerous outdated pages within google that were indexed dating back to 12/2004. In other words, you never know when or where and older page will be deleted from the search engine, so we maintaining them until the new page is indexed.

Will this "noindex,follow" command prevent a page from being droped from the index?
