 * I am thinking to change my permalink structure to something different which can’t
   be described with regular expression, so I can’t use a plugin like “redirection”
   to set the thing up.
    I want to change it from: /%year%/%monthnum%/%postname%.
   html to /%hour%%minute%%second%/%postname%
 * The thing is that on my newly installed blog with the same version of wordpress,
   if I change the permalink structure, and visit the old URL, it redirects to the
   new permalink automatically! I don’t know how it does it, but it works.
    However,
   with my old blog, it doesn’t work like that. I get a 404 page when I change the
   structure. Do anyone know why two different behaviours with two same version 
   of wordpress and how I can fix the old blog to react like the new blog and redirect
   to the new permalink structure automatically?
