Due to the domain rules, it is not possible to change the domain name after registration.
However, it is possible to register a new domain and then transfer the contents of the old domain to the new domain name.
It is also possible to add one domain as an alias for another domain, after which the address of the first domain will display the same content as the second domain.
How to add one domain as an alias for another domain, read the article.
