Upgraded My Personal Account to an Enterprise and Lost Access to All My Files

I recently needed to upgrade my cloud storage from the base 100gb to the 1tb plan. After going through the process of upgrading I opened illustrator like always and was prompted to sign in. After signing in I found that all my files were gone. After some investigation I found that all my files are still linked to my personal account (no longer active), and not my enterprise account.

But here's the rub: my enterprise account and personal account are under the same email.  Thise means I can't give my personal account access through the enterprise account admin portal.

Am I missing something? I was never prompted to auto migrate my files and I can't find a way to transfer files outside of individually giving access to each and every file (remember, there's over 100gb of files to transfer). I need access to these files ASAP and can't figure out a solution that isn't hugely time consuming.
