I quite understand if it is assumed, we started writing in 2010, then we changed the permalink structure in the same year (2010).
In the cases I mean, we started writing in 2008 and changed the permalink structure in 2010. And than we need to redirect all posts with htaccess.
Is it still possible to use these RedirectPermanent? as i knew that redirection syntax is
RedirectPermanent URL_path new_absolute_URL
