h2. Commands

h3. Make backups

First backup the tables that we will be modifying:

bq. mysqldump -u amber -p --skip-lock-tables --extended-insert redmine boards > boards-preport.sql

bq. mysqldump -u amber -p --skip-lock-tables --extended-insert redmine messages > messages-preport.sql

h3. Add temporary columns to the boards and messages tables

<pre>

ALTER TABLE boards

ADD bb_post_id int(11);

ALTER TABLE messages

ADD bb_forum_id int(11);

</pre>

h3. Add forums 

<pre>

INSERT INTO redmine.boards (project_id, name, description, topics_count, messages_count, bb_forum_id)

SELECT redmine.projects.id, bb2.notre_forums.forum_name, bb2.notre_forums.forum_desc, bb2.notre_forums.forum_topics, bb2.notre_forums.forum_posts, bb2.notre_forums.forum_id

FROM redmine.projects, bb2.notre_forums

WHERE redmine.projects.identifier="leginon" 

</pre>

Inserts 9 rows.

h3. Add Messages

<pre>

INSERT INTO redmine.messages (board_id, subject, content,  locked, sticky, bb_post_id)

SELECT redmine.boards.id, bb2.notre_posts.post_subject, bb2.notre_posts.post_text, bb2.notre_posts.post_edit_locked, 0, bb2.notre_posts.post_id

FROM bb2.notre_posts, redmine.boards

WHERE bb2.notre_posts.forum_id = redmine.boards.bb_forum_id;   

</pre>

inserted 603 rows.

h3. Add parent_id to messages

<pre>

UPDATE redmine.messages

SET redmine.messages.parent_id=redmine.messages.id

WHERE redmine.messages.id IN

(

 SELECT redmine.messages.id 

 FROM redmine.messages 

 WHERE redmine.messages.bb_post_id IN

 (

  SELECT bb2.notre_topics.topic_first_post_id

  FROM bb2.notre_topics

  WHERE bb2.notre_topics.topic_id IN

  (

   SELECT bb2.notre_posts.topic_id

   FROM bb2.notre_posts, redmine.messages

   WHERE redmine.messages.bb_post_id = bb2.notre_posts.post_id

  )

 )

); 

</pre>

To avoid a "bug with mySQL":http://emg.nysbc.org/projects/amigroup/wiki/Mysql_Nested_Subqueries_Problem , rewrite the above query:

<pre>

UPDATE redmine.messages

SET redmine.messages.parent_id=

(

 SELECT r_messages.id 

 FROM (SELECT * FROM redmine.messages) AS r_messages  

 INNER JOIN 

    (

    SELECT bb2.notre_topics.topic_first_post_id AS TopicFirstPostId 

    FROM bb2.notre_topics 

    INNER JOIN 

        (         

        SELECT bb2.notre_posts.topic_id AS TopicId 

        FROM bb2.notre_posts, redmine.messages 

        WHERE redmine.messages.bb_post_id=bb2.notre_posts.post_id 

        ) AS TopicIds 

    ON bb2.notre_topics.topic_id=TopicIds.TopicId 

    ) AS TopicFirstPostIds 

 ON r_messages.bb_post_id=TopicFirstPostIds.TopicFirstPostId

);

</pre>

h3. Convert Unix timestamps to ISO 8601 and add to messages

bb2.notre_posts.post_time, bb2.notre_posts.post_edit_time,

http://aruljohn.com/timestamp2date.html

h3. Add author_id to messages

h3. Add replies_count to messages

h3. Add last_reply_id to messages

h3. Create a backup of the tables

bq. mysqldump -u amber -p --skip-lock-tables --extended-insert redmine boards > boards-postport.sql

bq. mysqldump -u amber -p --skip-lock-tables --extended-insert redmine messages > messages-postport.sql

h3. Remove the temporary columns

<pre>

ALTER TABLE boards

DROP COLUMN bb_post_id;

ALTER TABLE messages

DROP COLUMN bb_forum_id;

</pre>
