Our dental blog WURZELSPITZE, dedicated to enodontics, has been in existence since 2008 and we have now published more than 3000 posts, amassing an enormous amount of knowledge and expertise. Until now, the blog was classified as private on Wordpress and therefore reserved for members who paid an annual fee. Now we want to make the blog accessible to all dental professionals who donate at least a small monthly amount. However, the 3000 legacy articles should be readable exclusively by our premium level patrons to prevent readers from logging in for a short time and little fee and then quitting. Is there a setting that classifies all existing 3000+ posts as premium level content ? Without having to manually set this for each of the 3000 posts ?
Thanks in advance for any advice . I am very grateful for the all the help !
Kind regards
