Use this tool to transfer database items between two different Joomla! sites, or duplicate items within your live site. This is a ‘mass’ copy/paste tool necessary for ALL Joomla! administrators.
In the old Joomla! 1.5 when you wanted to transfer database items to a different Joomla, just an export/import of the required database tables would do the job. With the new Joomla! 1.6, 1.7, 2.5, 3.0 and above, this is no longer possible.
This tool is doing just exactly that.
