What is domain name transfer?
It usually refers to transferring a domain name from one domain registrar to a new one. The original domain registrar is generally called the "transfer-out party," while the new domain registrar is referred to as the "transfer-in party." There are many reasons for transferring a domain, such as renewal fee prices, lack of features, domain registration requirements, or the need to unify domain and hosting management, or to change the owner, etc. The process of transferring a domain out is also known as "domain name transfer."
Will DNS resolution be affected during the domain transfer process?
First, we need to confirm the purpose of the domain. If it is for trading, parking, display pages, etc., then the impact of resolution during the transfer process is almost negligible. If the domain is for a large website with significant traffic, then the domain transfer should be approached with caution. This is because it involves three service provider roles: the "transfer-in registrar," the "transfer-out registrar," and the "DNS resolution service provider." Here are several scenarios:
(1) If the "transfer-in registrar," "transfer-out registrar," and "DNS resolution service provider" are all independent, for example, the "transfer-in registrar" is Aiming Network, the "transfer-out registrar" is GoDaddy, and the "DNS resolution service provider" is DNSPOD,
then the resolution will not be affected at all during the transfer process, as the domain DNS is not changed during the transfer.
(2) If the DNS resolution uses the DNS of the "transfer-out registrar" and the domain has a large amount of traffic or applications with uninterrupted business requirements, for caution, the following operations can be performed:
(2.1) Export and back up all resolution records.
(2.2) Contact the transfer-in registrar first and add the resolution records to the transfer-in registrar. If the transfer-in registrar is also a DNS provider, you can import the records yourself.
(2.3) Proceed with the domain transfer. Once the transfer is successful, immediately synchronize the resolution or check the effectiveness of the resolution.
(3) When transferring to a new registrar, there is generally an option to change or not change the current domain DNS. This should be operated according to your actual needs. If it is a third-party DNS service, do not select this option. Because if you select it, the DNS will be changed immediately once the transfer is successful. If you have not timely resolved or pre-imported in the new registrar, a time difference will occur.
