Can I transfer my Google Apps mailbox to another Wix account?
It is currently not possible to transfer a Google Apps mailbox from one Wix account to another. In addition, it is not possible to transfer a Wix Domain which has an active Google Apps account attached to it.
In order to transfer a domain with a Google Apps account attached to it, you will first need to cancel the Google Apps account (if you have a monthly plan) or migrate the Google Apps account to be managed by Google and cancel the service on our end.
Once the Google Apps service is canceled, you will be able to transfer the domain to another Wix account.
