I have a new email. I cannot migrate from the old account because I don'r remember my password. How can I relate my old email account to my newly created ?
Giorgio. Of course you cannot migrate any data from an account you cannot access, that would be a very bad thing. So contact Adobe to help you regain access if you can prove ownership.
(Be aware that this answer does not apply unless you have an ENTERPRISE or TEAMS license. If you have an individual license, each one is separate; your account is only for you. Individual licenses are rarely a good idea for businesses with employees, since the company has no right to cancel or query the account).
