Change login email address or merge account

Hi there,
How can I change my dbdiagram login email address to another email address? Or can I merge two accounts into one? I need to discuss this with customer support.
Thanks.

Unfortunately, we haven’t supported changing the email address yet due to the subscription management system. We can help you by transfer the data from the old account to the new one.

The transfer process will take some effort. Hence if your account has few diagrams, you can do the transfer manually by copy & paste the DBML content.
