Cohorts backup and restore

Hi All, 

I am currently upgrading from Moodle 2.6 to Moodle 2.9. i am NOT doing a backup and restore of the site because it has a couple of lectures only. my question is how can i download a list of users with their corresponding cohorts. 'Bulk user action' downloads the list of users without their Cohorts. is there a way to solve this.

Thanks  Image may be NSFW.
