Hey guys, Basically, I currently have a wordpress blog to display posts as /p1234. Now my question is, if I change it to /%postname% will the search results in google still lead to the original page or will the user get a 404 error?
Or there used to be a plug in called Dean's Permalink Migration that was good for that. http://wordpress.org/extend/plugins/permalinks-migration-plugin-for-wordpress/ I haven't used it in a while, but it appears to be still compatible.
