Adobe allows users to graduate to migrate their colum.edu content to personal adobe accounts free or paid after graduation. Graduating students will have access to their Adobe account for 90 days after graduation. Please use this time to migrate any content you would like to keep to another free or paid account.
Please visit https://graduation.adobe.com/ to start the process.
The detailed process is shown in the adobe article below
