I started with the default permalink structure e.g. mydomain.com/?p=273 Now I want to edit my permalink structure to be more search engine friendly e.g. mydomain.com/archives/%post_id% However, I already have 273 posts and can't afford to break all the links to my old posts. How can I update my permalink structure without breaking my old links? I feel that there should be a way to update the permalink structure and have it apply only to all future posts. What are my options? I've searched all over and haven't found anything helpful. Thanks so much!
