I have a WP site with data to some date, and a more relevant export with the latest posts etc. I need to import this last one.
From what I see in the export:
( ) All content - This will contain all of your posts, pages, comments, custom fields, terms, navigation menus and custom posts.
So my configuration shouldn't be at risk.
But I still would like to not have duplicate content, I'm talking about a lot of posts, comments, pages etc, too many to be checking manually and removing duplicates one by one.
Is there a user-friendly way to cleanup an obsolete WP before importing? Or which tables should I truncate?
