The email address you associate with your Redgate ID cannot be changed in the customer portal. If you change your email address please follow these steps:
You will first need to create a Redgate ID for the new email address that you'd like to use.
Once you've created the Redgate ID and logged into the customer portal using your new email address, you can request ownership of your existing licenses in the customer portal by clicking add existing license at the top of the My Products page. You will need to know the serial number(s) for your license(s). A request will be sent to your pre-existing email address asking for the ownership of the license(s) to be accepted or rejected. Use the link in the email to accept or reject the request.
If you do not have access to the old email address's inbox and therefore you can't respond to the request, it shall pend for 10 days before automatically accepting.
Once accepted, you'll be able to see the licenses in your account and manage and distribute them as you wish.
