I have a client for whom I'm developing a new WP site. Their current site uses DNN but due to security reasons (among others) they have chosen WordPress.
As we are migrating and updating blog content there are many internal links pointing to pages in their old site.
Their url structure is: https://www.example.com/resources/blog-name/title-of-post
However in the new site the structure will be: https://www.example.com/blog-name/title-of-post
What is the best way to deal with this? Should we go in the dev server as we are transferring content and just change the links manually with the future address in mind?
Also, should I be using 301 redirects? We understand that we will take an SEO hit but I want to make sure I minimize this and I am looking for some tips/advice since we have over 1000 articles.
