The following settings for your assignments will not transfer post-migration. You will want to record these settings to recreate them in your Luminate assignments:
File Attachments
Release Conditions
All Submission & Completion Settings (e.g., associated groups)
All Evaluation & Feedback Settings (e.g., associated rubrics)
Since rubrics and groups do not transfer post-migration, they will need to be recreated before they can be associated with your assignments.
