How to Transfer a Domain Between Teams
We do not have an option to directly transfer domain ownership from one team to another. Instead, you can download a zone file with all of the domain’s DNS information. Once downloaded, delete the domain from the old team, add it to the new team, then copy and paste the DNS records from the zone file into the domain in the control panel.
You can find the Download Zone option by clicking the More button to the side of your domain name in the Networking tab.
