if you use the PHP-myadmin, you should EXPORT an sql dump of ALL your tables, and then IMPORT the same sql.
If I understand correctly (and maybe I am wrong) you try to import CSV into an SQL dump .. that will not work in direct sql dump.
after you have the sql dump, use the following :
/**
UPDATE wp_options SET option_value = REPLACE(option_value, 'http://www.old-domain.com', 'http://www.new-domain.com') WHERE option_name="home" OR option_name="siteurl";
/**
After that you will need to fix URLs of the WordPress posts and pages, which translated from post slug, and stored in database wp_posts table as guid field. The URL values in this field are stored as abolute URLs instead of relative URLs, so it needs to be changed with the following SQL query:
**/
UPDATE wp_posts SET guid = REPLACE(guid, 'http://www.old-domain.com','http://www.new-domain.com');
/**
If you have linked internally within blog posts or pages with absolute URLs, these links will point to wrong locations after you move the blog location. Use the following SQL commands to fix all internal links to own blog in all WordPress posts and pages:
**/
UPDATE wp_posts SET post_content = REPLACE(post_content, 'http://www.old-domain.com', 'http://www.new-domain.com');
