I am moving to a new ID in IBM due to transferring countries

Hi Said, 

Welcome to Box Community and glad to help! 

To transfer your contents from one user to another, here's the steps: 

To transfer the folder ownership: 

• Locate the appropriate folder 
• Click the Collaboration Icon to the right of the file name.
• Alternatively, you can open More Options > More Actions and select Manage Collaborators.
• Find the collaborator whose access level you would like to modify. You can search by name using the Filter Collaborators search box in the upper right.
• Under the Permissions column, click the user's access level to modify it. Select Owner as the appropriate access level from the dropdown to transfer ownership. 

Note: You can only transfer the folder ownership to your existing collaborator. 

Transferring Folder Ownership

If you are the owner of a folder, you can transfer folder ownership to a collaborator at any time. Simply follow the instructions above, and select Owner from the access level dropdown (this option is only visible to folder owners). The collaborator you designate will be the new "Owner" of the folder and your access level will be downgraded to "Editor". The contents of the folder will no longer count against your account's storage allowance.

Hope it helps! For clarifications, you may open a ticket and work directly with our Support team.
