I am in the process of the optimising site for different keywords. That means that I am changing URL of exsitgin posts.

For example : femdomdestiny.com/strapped-down-and-exposed/ is now renamed to : femdomdestiny.com/balls-torture-with-clamps/.

I was wondering what is happening with internal links going to the old version of link? I ve just fugred out that WP alone is automatically redirecting to the new link. That is fine and I guess it is default Wp feature?
What bothers me is that on page where is link to the old version of URL still goes there. This is the example:

Femdom Torture and Brutal Leather Boots Worship (word CLAMPS) is linked to the old version.

Questions is how this affects SEO?
Is there a way to automatically change link on all pages on site into new and updated version?

thanks
