Commands¶

Make backups¶

First backup the tables that we will be modifying:

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

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

Add temporary columns to the boards and messages tables¶

ALTER TABLE boards
ADD bb_post_id int(11);

ALTER TABLE messages
ADD bb_forum_id int(11);

ALTER TABLE messages
ADD bb_topic_id int(11);

ALTER TABLE messages
ADD bb_topic_first_post_id int(11);

Add forums¶

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" 

Inserts 9 rows.

Add Messages¶

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;   

inserted 603 rows.

Add bb_topic_id to messages¶

UPDATE redmine.messages, bb2.notre_posts
SET redmine.messages.bb_topic_id=bb2.notre_posts.topic_id
WHERE redmine.messages.bb_post_id = bb2.notre_posts.post_id;

Add bb_topic_first_post_id to messages¶

UPDATE redmine.messages, bb2.notre_topics
SET redmine.messages.bb_topic_first_post_id=bb2.notre_topics.topic_first_post_id
WHERE redmine.messages.bb_topic_id=bb2.notre_topics.topic_id;

Add parent_id to messages¶

UPDATE redmine.messages AS redMess1, redmine.messages AS redMess2
SET redMess1.parent_id=redMess2.id
WHERE redMess1.bb_topic_first_post_id=redMess2.bb_post_id;

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

Add author_id to messages¶

UPDATE redmine.messages, redmine.users, bb2.notre_users, bb2.notre_posts
SET redmine.messages.authorid=redmine.users.id
WHERE redmine.messages.bb_post_id = bb2.notre_posts.post_id
AND bb2.notre_posts.poster_id=bb2.notre_users.user_id
AND bb2.notre_users.user_email = redmine.users.mail;

Add replies_count to messages¶

Add last_reply_id to messages¶

Create a backup of the tables¶

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

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

Remove the temporary columns¶

ALTER TABLE boards
DROP COLUMN bb_post_id;

ALTER TABLE messages
DROP COLUMN bb_forum_id;

ALTER TABLE messages
DROP COLUMN bb_topic_id;
