I create a new system for converting the database of another blog in Typo blog database. My new system is base on Mephisto converter. It's a plugin and he use completly ActiveRecord. For retrieve the information on other blog and post in typo.

Now, the converter works only with Dotclear, but an interface is write and you can use it with another Blog engine to create another adapter.

To start the migration with dotclear, you need complete the config/database.yml with an configurations with dc key and all information on where find the database with SQLDump of your blog engine. After this configuration you can start the migration with the follow commande line :

./script/runner 'TypoPlugins.convert_from :dotclear'

By default all articles migrated, but you can migrate only articles with specifiques categories.

./script/runner "TypoPlugins.convert_from :dotclear, {:categorie => ['ruby', 'rails', 'dev']}" 

Advice : To accelerate the migration you can comment in
config/environnement.rb the line of Observer :

#config.active_record.observers = :email_notifier, :web_notifier
