Cloudflare Registrar domain registration between accounts- Now Self-Serve!
Hi there,
We appreciate your patience regarding your recent ticket. Due to an increase in support requests and due to our engineering team working on this request, we’ve experienced a slight delay in resolving issues. However, we have some great news!
Cloudflare Registrar domain registration between accountsare now a self-serve process, conveniently accessible through your dashboard.
Here’s how to easily move your Cloudflare Registrar domain registration: Go to Domain Registration> Manage domains> Configuration>Move to another Cloudflare account>Start
Note: Our documentation will be updated shortly to reflect this change.
We hope this simplifies the domain registration move process! We’ve marked this ticket as resolved, but feel free to reply if you encounter any issues or have additional questions.
在manage domain的右侧，出现了Move to another account 的选项。
大体流程是原账号操作后，新账号接收就可以了。

Unable to transfer, not officially supported
转不了，官方不支持！
虽然cloudflare给了屌丝们众多福利，但是这个功能就是不支持，主打一个头铁，看样子以后也不会支持。

You cannot move a domain registration directly to another account, but that needn’t prevent you from moving the domain to another Cloudflare account.
It currently does require transferring the domain registration to a third-party party registrar temporarily. If you want to move registration back to Cloudflare, you certainly can after the sixty day transfer lock expires.
Cloudflare staff know about this topic and have been aware of this limitation for the five years that the Cloudflare registrar has been in operation. While it is a shortcoming that Cloudflare has publicly acknowledged that they would like to improve, it isn’t something that I expect to see change any time soon.
I recommend operating under the assumption that the ability to transfer domain registration directly between Cloudflare accounts will never be available. It will reduce disappointment and force the use of practices that work within the limits of the current design.
