change email account

Hi,

We've recently changed our company's domain, so all the Adobe accounts are with the old email accounts. Is there any way to update the Adobe accounts with a new email without deleting the original ID?  I ask this as many of our users have some significant amount of information on the Creative Cloud, and I would need to migrate that information somewhere before I delete the user, and reassign a new email account.

Thanks for your help
