It depends on how complex you want the redirect to be. Are you saying you want any of the 50+ pages to redirect to the homepage of a new site, or are you saying that you have an alternative URL for each of the 50+ pages?
If the latter is the case (and there is the same folder hierarchy), some sort of mod_rewrite solution is probably the way to go. Otherwise, you may be able to accomplish the task with some simple redirects in your .htaccess file.
