Fixing categories missed in WordPress upgrade

Apperantlly the wp_terms table was not converted while i updated the WordPress installation to the latest. so i had to do it manually
here is how.
I logged in to the SQL admin and ran these 2 SQL commands
INSERT INTO wp_terms (term_id, name, slug, term_group) select tag_id,tag,tag,0 from wp_tags;

to get the categories across and then

INSERT INTO wp_term_relationships select tag_id, post_id,0 from wp_post2tag

the only table that i need to write code to fix is the taxonomy extended table which is more like elaboratoin of the tags.

Update!
I have managed to solve the extended taxonomy using a help from Jamine Kapish who wrote a full import script.
i have ran alteration of his script written based on his script i found in this post
define('DBNAME', '?'); // The name of the database define('USERNAME', '?'); // Your MySQL username define('PASSWORD', '?'); // ...and password define('HOSTNAME', '?'); /* DO NOT CHANGE ANYTHING AFTER THIS UNLESS YOU KNOW WHAT YOU ARE DOING */ $conn = mysql_connect(HOSTNAME, USERNAME, PASSWORD); if (!$conn) { echo "Unable to connect to DB: " . mysql_error(); exit; } if (!mysql_select_db(DBNAME)) { echo "Unable to select DATABASE : " . mysql_error(); exit; } $wptagsQuery = "SELECT * FROM wp_tags"; $wptagsResult = mysql_query($wptagsQuery) or die(mysql_error()); while ($wptagsRow = mysql_fetch_assoc($wptagsResult)) { $terms_id = mysql_insert_id(); $countPostsQuery = "SELECT count(post_id) AS countPosts FROM wp_post2tag WHERE tag_id = " . $wptagsRow["tag_ID"]; $countPostsResult = mysql_query($countPostsQuery) or die(mysql_error()); $countPostsRow = mysql_fetch_assoc($countPostsResult) or die(mysql_error()); $termsTaxonomyInsertQuery = "INSERT INTO wp_term_taxonomy (term_taxonomy_id, term_id, taxonomy, description, parent, count) VALUES (0, $terms_id, 'post_tag', '', 0, ".$countPostsRow["countPosts"].")"; echo $termsTaxonomyInsertQuery; $termsTaxonomyInsertResult = mysql_query($termsTaxonomyInsertQuery) or die(mysql_error()); } ?>

Hope this helps.
