Conversion tables¶

Redmine Users¶

Search for the user to have an existing entry, if not their posts will be assigned to anonymous.

Redmine Entry	BB Entry
id
login	notre_users->username
hashed_password
firstname
lastname
mail	notre_users->user_email
mail_notification
admin
status
last_login_on
language	notre_users->user_lang
auth_source_id
created_on
updated_on
type
identity_url

Redmine Boards¶

We will create these from scratch - Development, Using Leginon, Using Appion, Tomography, Installation, Administration Tools

Redmine Entry	BB Entry
id
project_id	(the leginon id)
name	notre_forums->forum_name
description	notre_forums->forum_desc
position
topics_count	notre_forums->forum_topics
messages_count	notre_forums->forum_posts
last_message_id	After all messages are ported add: notre_forums->forum_last_post_id->Redmine Messages->bb_post_id->id
bb_forum_id	notre_forums->forum_id

Redmine Messages¶

Redmine Entry	BB Entry
id
board_id	notre_posts->forum_id->Redmine Boards->bb_forum_id->id
parent_id	Add these as second step after all posts moved over, notre_posts->topic_id->notre_topics->topic_first_post_id->Redmine Messages->bb_post_id->id
subject	notre_posts->post_subject
content	notre_posts->post_text (need to get BLOB)
author_id	notre_posts->poster_id->notre_users->user_email->Users->mail->Users->id, if does not exist assign to anonymous
replies_count	Set all to 0 then check Notre_topics->topic_first_post_id and update that message with Notre_topics->topic_replies
last_reply_id	Set all to NULL then check notre_topics->topic_first_post_id->Redmine Messages->bb_post_id->id and update that message with notre_topics->topic_last_post_id->Redmine Messages->bb_post_id->id
created_on	notre_posts->post_time (may need a conversion)
updated_on	notre_posts->post_edit_time (may need a conversion)
locked	notre_posts->post_edit_locked
sticky	0
bb_post_id	notre_posts->post_id

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);

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 parent_id to messages¶

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
  )
 )
); 

To avoid a bug with mySQL , rewrite the above query:

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
 WHERE r_messages.bb_post_id = redmine.messages.bb_post_id
)
WHERE redmine.messages.bb_post_id IS NOT NULL;

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¶

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;
