Renaming url structure and redirects

[Gemini23]

On a website I currently have a folder where the Wordpress installation is

greatgreenwidgets
that I would like to amend to
great-green-widgets

and also
currently have permalink structure of
/index.php/%post_id%/%postname%/

that I would like to change to 'Post Name'
ie sample-post/


Is it possible to do either of the above WITHOUT causing 404 errors?
ie via redirects etc in the htaccess?

All things are possible with redirects in htaccess ;) Subforum next door. But before you do that, look for WP plugins to do what you want.

No point in reinventing the wheel.

Redirection plugin - very handy.

Wouldn't it be faster and easier if you will install fresh/clean WP and use your old database. Everything should work fine from there.

The WP installation actually redirects automatically... :)
