Hello [sorry for cross-posting],
It is now possible to convert Moodle 1.9 courses into Moodle 2.0 via the online Moodle 1.9 to Moodle 2.0 Course Converter, a script written by Catalyst IT. We opened the online converter up for anybody to use now instead of only the Moodle in NZ Schools community.
That development work was made possible through funding from the NZ Ministry of Education.
The course converter only converts the content and activities as they are available in the Moodle in NZ Schools version plus the Hot Potatoes module. Thus, if you have a course with a module that is not yet supported by the Moodle in NZ Schools version, e.g. Stamp Collection, these activities will not be converted.
The converter works to the best of our knowledge. We will do our best to answer questions from people who use the converter and run into problems, e.g. not get an email with the file.
We will make the code of the converter available to the Moodle community so that others can install it on their own server instead of using the online converter. This code should be available within the next 2 weeks.
