If you are changing the old permalink structure of your website, or changing any specific post link, then you will need to redirect the old url to new link with 301 redirect, it is a permanent redirect, and it is required to protect your seo efforts. If you will not do it, the link juice of old link will be lost. So it is a best practice to always use the 301 redirects.
