Will changing WP permalink custom structure affect old posts URL?
For example. I have a large group of posts that follow this custom structure: /blog/%category%/%postname%/
I want to change it to /blog/
Or better yet, be able to manually add structure after the root domain for every post.
So that I have the option to manually enter /%category%/%postname%/
I'm hoping that changing my permalink custom structure will only affect new posts going forward and old posts remain unchanged.
