Recently, I've saw MTW Migrator for Joomla.
It seems to me easy migration content from old version to new version of website. Just type database name, passs and localhost and migrator do the thing
Could it be nice when Drupal have the similar module.
I would love to transfer all content from my old Drupal 5 to new installation of Drupal 7. It would be great when I could install similar module and easily transfer all articles to my new Drupal 7 site.
