Now suddenly the business requires to replace the website and build a new more interactive website having new structure. Now since this website was already live and you had visitors to your previous 5 pages, a change in structure would mean these 5 indexed pages can not be found by search engines. This will in turn hit the rankings of your website. This is where a 301 permanent redirect comes into picture. It is a friendly way to let search engines know that sorry this page is no more active and the new location is this page.

Another reason to use this type of permanent redirect is to let search engines know the destination when an invalid indexed URL is looked for like redirecting the users to a standard page which says the resource you are looking for cannot be found.
