Moodle 2.0

The goal of this page is to provide a checklist of tasks to be considered to upgrade CONTRIB code to Moodle 2.0. Several significant changes have taken place including the File API, DB Layer, Navigation, Output renderer, etc. It would be good if we had a list that contributors could follow to help move them toward being able to migrate the code. Any help in building up this list is greatly appreciated.

Please add useful links...

Backup and Restore
