There’s a new Moodle 1.9 to 2.0 conversion tool available to use freely which was developed with support from the New Zealand Ministry of Education (http://www.minedu.govt.nz). The converter works on each of the standard Moodle features/modules and supports Hot Potatoes as well. According to the post at Moodle.org [link],
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.
All you need to do is upload your Moodle 1.9 file and provide your email address. Once the conversion has finished, you will receive an email with a download link.
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.
We’ll do some testing this week to highlight the ease of use and any pitfalls you should be wary of but it does look like an extremely easy to use two-step process. Until then this is a great opportunity to give your Moodle conversion a try at http://www.moodleinschools.org.nz/courseconverter.
