Just a quick clarification about http://www.conversionthingy.net/ : it doesn't convert user data, only resources. Basically, it's only intended to convert old 1.9 zip backup file to 2.0 mbz backup files. But from 2.1 this process is completely managed by moodle itself. So, altough the programm works well in the conversion process, you shouldn't need this program to restore a backup file from 1.9 to 2.1 upwards.
