- * Transfers a domain name from another registrar to Cloud Domains.  For
- * domains managed by Google Domains, transferring to Cloud Domains is not
- * supported.
- *
- *
- * Before calling this method, go to the domain's current registrar to unlock
- * the domain for transfer and retrieve the domain's transfer authorization
- * code. Then call `RetrieveTransferParameters` to confirm that the domain is
- * unlocked and to get values needed to build a call to this method.
- *
- * A successful call creates a `Registration` resource in state
- * `TRANSFER_PENDING`. It can take several days to complete the transfer
- * process. The registrant can often speed up this process by approving the
- * transfer through the current registrar, either by clicking a link in an
- * email from the registrar or by visiting the registrar's website.
- *
- * A few minutes after transfer approval, the resource transitions to state
- * `ACTIVE`, indicating that the transfer was successful. If the transfer is
- * rejected or the request expires without being approved, the resource can
- * end up in state `TRANSFER_FAILED`. If transfer fails, you can safely delete
- * the resource and retry the transfer.

- * A successful call creates a `Registration` resource in state

- * email from the registrar or by visiting the registrar's website.
- *
- * A few minutes after transfer approval, the resource transitions to state
- * `ACTIVE`, indicating that the transfer was successful. If the transfer is

- * end up in state `TRANSFER_FAILED`. If transfer fails, you can safely delete
