Transferring an existing domain entails changing the registrar company that handles the domain name registration service, so after the transfer itself, you will have to manage things like renewal fees or DNS modifications through the new company. The transfer process itself is standard with most domain extensions. Certain country-code extensions are more specific and entail different procedures, but in the general case transferring a domain name involves a few basic steps and one of them is unlocking the domain. The lock is a safety option, which is being adopted by more and more domain name registry operators. It’s a default feature supported by all generic Top-Level Domains. If a domain is locked, it won’t be possible to initiate a transfer procedure, so no one can even try to register your domain. The domain lock can be annulled only through the account where the domain name is registered in the first place and all new domain names that support this feature are locked by default when they are registered.
