Moving Wordpress to another domain with different permalinks

I want to move Wordpress to another domain and also change the permalinks. So basically what I want is to move from: oldsite.开发者_运维问答com/PostId-PostName.html to newsite.com/PostName/

I know this can be done from .htaccess, but I don't manage to get it right. Can you please help me ?

This is how it can be done using Apache's mod_rewrite:

# Activate Rewrite Engine
RewriteEngine On
# redirect posts to new site
RewriteRule ^(\d+)-([^/]+)\.html http://www.newsite.com/$2/ [R=301,NC,QSA,L]

This will ONLY redirect URLs like oldsite.com/12345-very-interesting-post.html.

There is a Codex article dedicated to this: Moving WordPress
