Moodle will be maintained through the course of the 2014-2015 academic year. Moodle will not be upgraded (just patched with security updates) so it will not change again from the current version. At the end of spring quarter Moodle will be discontinued as a learning management system (LMS) for the college but the data will continue to be available to faculty for at least a year from this date.
Canvas, as a cloud service, is updated every 3 weeks and so as such is a dynamic and changing environment. We will be doing faculty trainings throughout the year, check out my.evergreen.edu for a link to the faculty orientation course and information about training schedules. We look forward to the new opportunities with Canvas!
