Yale BOX migration (at YSM only) will start at 5:00pm on February 20, 2026, and will run until completed.

Users will be divided into 6 migration phases (See above) based on the total number of files and the overall data size of the BOX account:

Explanation on why the number of files matter and what you can do to reduce the number of files.

How to Delete files in your Yale BOX Account - to speed up your migration

Your Yale BOX account will be set to “Inactive” once the files are migrated from Yale BOX to OneDrive, and we verify there were no errors during migration.  Once the account is set to “Inactive” you will not be able to access your Yale BOX account - this is to prevent accidental modifications of the same document in two places by you or anyone you have shared documents with in BOX.

You can have your Yale BOX account restored to “Active” by calling the Yale ITS helpdesk at 203 432-9000.  However, you will be responsible for archiving or migrating documents in your Yale BOX account once it is activated again.  We will not migrate your files for you.

If someone is sharing files with you via BOX who is outside of Yale - when we migrate your Yale BOX account to OneDrive and set your Yale BOX account to “Inactive”, you will not be able to access those shared files.  To restore access to your Yale BOX account you can call the ITS helpdesk at (203) 432-9000.

However, when Yale BOX is retired at the University (March 31, 2026), you will lose access to your Yale BOX account and those shared files.  We highly recommend that you find alternative sharing methods for files shared to you by people outside of Yale.  We recommend the person sharing files with you use OneDrive or Teams to share files with you.

After we migrate your BOX account, you can still access your files, but once Yale BOX and Secure BOX is retired on March 31, 2026, you will not be able to access these files via BOX.

If you do not want your Yale BOX files to be migrated, then you should delete ALL your files in Yale BOX prior to the YSM migrations - see above for schedule.

Please note: When Yale BOX is retired on March 31, 2026 - the vendor will delete your files.  

To delete your files in BOX - it is a 2 step process:

Step 1: In Yale BOX, click on the selection box to the right for all files and folders and then click on the “Trash” button.  This moves the files to the trash but does not delete them.

Step 2: Go to the “Trash” folder in Yale BOX on the left and then click the “Delete All” button.  This will delete all files in the trash.

Yes, OneDrive is an acceptable location to store high risk data files.  It has the same security safeguards as Secure BOX.

OneDrive uses a shared responsibility model meaning it is OK to put High Risk data in OneDrive, but if you accidentally share that high risk data to someone, the responsibility of that action falls to you.
