how to migrate cmsms news + comments to cgblog

Thanks to Gregor for the original tutorial, found on the cmsms forum.

I've been using the combination news + comments as a sort of blog module. Because of the existence of CGBlog, I wanted to migrate my data to cgblog. In the following part, I'll show/explain what I have done.

Thanks to Gregor for the original tutorial, found on the cmsms forum.

The basis is to keep the numbering of news articles equal to cgblog articles. This because it helps you to 'link' comments being made to the blog article.

0. Create a backup of the database and store it in a safe place!!!!
1. Install CGBlog
2. Insert News-items into CGBlog. Replace 'Your Name' with the writer of the article. In this case, all articles are written by me. If you have more writers, you have to add these names manually.

insert into cms_module_cgblog
(`cgblog_id`, `cgblog_title`, `cgblog_data`, `cgblog_date`, `summary`, `start_time`, `end_time`, `status`, `create_date`, `modified_date`, `cgblog_extra`, `url`)
select
`news_id`, `news_title`, `news_data`, `news_date`, `summary`, `start_time`, `end_time`, `status`, `create_date`, `modified_date`, `news_extra`, NULL
from cms_module_news

3. First, delete all rows from the cgblog_category table, so you have an empty table. Manual action.
4. Insert the news categories into the cgblog categories:

insert into cms_module_cgblog_categories
(`id`, `name`, `parent_id`, `hierarchy`, `long_name`)
select
`news_category_id`, `news_category_name`, `parent_id`, `hierarchy`, `long_name`
from cms_module_news_categories

5. Insert the relation between the blog categories and the news categories:

insert into cms_module_cgblog_blog_categories
(`blog_id`, `category_id`)
select
`news_id`, `news_category_id`
from cms_module_news

6. If you have made any field definitions in News, insert these into field defs. from the cgblog module:

insert into cms_module_cgblog_fielddefs
(`id`, `name`, `type`, `create_date`, `modified_date`, `item_order`, `public`, `attrs`)
select
`id`, `name`, `type`, `create_date`, `modified_date`, `item_order`, `public`, `extra`
from cms_module_news_fielddefs

7. Insert the field values, if any:

insert into cms_module_cgblog_fieldvals
(`cgblog_id`, `fielddef_id`, `value`, `create_date`, `modified_date`)
select
`news_id`, `fielddef_id`, `value`, `create_date`, `modified_date`
from cms_module_news_fieldvals

8. Make sure you add the correct sequent number:

insert into cms_module_cgblog_seq
(`id`)
select
`id`
from cms_module_news_seq

9. Change the author collum for every post, to your desired username. (new usernames won't be like this unless you manually change it)

UPDATE cms_module_cgblog SET author = 'Admin'

Sometimes you need to update the "cms_module_cgblog_seq", as it will be showing the wrong number when making a new cgblog news.

You need to export the cms_module_cgblog_seq and edit the number, then delete the existing table, then import the working number version.
