[Web Development] Migrating DedeCMS to Discuz Portal

Fri, 18 Nov 2016 05:14:05 +0000

I recently needed to migrate from DedeCMS (dedecms) to Discuz Portal. The most important challenge was how to migrate categories and a large number of articles.

The database tables involved are:

dede_addonarticle - Article table
dede_arctype - Category table
dede_relation - Old-to-new category mapping table
pre_portal_article_content - Article content table
pre_portal_article_title - Article title table
pre_portal_article_count - Article view count table

1. Preprocess the old table, merge `typename`

1
2
3


UPDATE dede_addonarticle, dede_arctype
SET dede_addonarticle.typename = dede_arctype.typename
WHERE dede_arctype.id = dede_addonarticle.typeid;

2. Merge `click`, `title`, `writer`, `pubdate`, `keywords`, `description`

UPDATE dede_addonarticle, dede_archives
SET
 dede_addonarticle.click = dede_archives.click,
 dede_addonarticle.title = dede_archives.title,
 dede_addonarticle.writer = dede_archives.writer,
 dede_addonarticle.pubdate = dede_archives.pubdate,
 dede_addonarticle.keywords = dede_archives.keywords,
 dede_addonarticle.description = dede_archives.description
WHERE dede_archives.id = dede_addonarticle.aid;

3. Generate new IDs in `relation`

1
2
3


UPDATE dede_relation, pre_portal_category
SET dede_relation.catid = pre_portal_category.catid
WHERE dede_relation.new = pre_portal_category.catname;

4. Populate `catid` based on `typename` and `relation`

3


UPDATE dede_addonarticle, dede_relation
SET dede_addonarticle.catid = dede_relation.catid
WHERE dede_addonarticle.typename LIKE CONCAT("%", dede_relation.olds, "%");

5. Import into Discuz Portal Tables

Insert into `pre_portal_article_content` (Article content table)

1
2
3


INSERT INTO pre_portal_article_content(aid, title, content, dateline)
SELECT aid, title, body, pubdate AS dateline
FROM dede_addonarticle;

Insert into `pre_portal_article_title` (Article title table)

INSERT INTO pre_portal_article_title(aid, username, title, author, summary, dateline)
SELECT aid, 'admin', title, writer AS author, description AS summary, pubdate AS dateline
FROM dede_addonarticle;

Insert into `pre_portal_article_count` (Article view count table)

INSERT INTO pre_portal_article_count(aid, cid, viewnum)
SELECT aid, catid, click
FROM dede_addonarticle;
