Will permalinks work if blog is transferred to subdirectory?

Question

How should I transfer my WordPress blog from the root of my domain to a sub-directory?

If everything including root in an installment of WP 3.2.1 were moved to a sub-directory, would the default permalink structure update to it? e.g. domain.com/wp-sub instead of wp-domain.com?

Also, should I modify any code or settings and, if so, what exactly?

Answer 1

Moving all files from root to a subdirectory will work.
Don't forget the .htaccess file.
Just after move the files, you should change the root path in Configuration -> General - Site address. To the right direction.

i.e. Moving from http://example.com to http://example.com/blog/

Answer 2

I think you should also run a few MYSQL queries to make it work:

UPDATE wp_options SET option_value = replace(option_value, 'http://example.com', 'http://example.com/blog') WHERE option_name = 'home' OR option_name = 'siteurl';

UPDATE wp_posts SET guid = replace(guid, 'http://example.com','http://example.com/blog');

UPDATE wp_posts SET post_content = replace(post_content, 'http://example.com/', 'http://example.com/blog');

If your permalinks are still not working, delete the .htaccess file, and go to Settings->Permalinks and click save to create the .htaccess file.
