We can make this change for customers with a commercial license. 

After you make sure what the final credentials you plan to use are, we can manually make the data transfer on our end.
Please, do not create a developer account with the new email address in the meantime. 

You can make the request by sending an email to sales@wikitude.com. Make sure you include:
- a summary of your request
- the old and new email address 
- confirmation that you want us to transfer the key (INV-) from (old email address) to (new email address) 
- confirmation that you want us to transfer the studio projects from (old email address) to (new email address)
