He trasladado dominios de un registrante a otro sin problemas cambiando de titular Y SIEMPRE ha sido el proceso igual:
1-Libero el dominio desde mi panel de control y le facilito al nuevo titular el AUTH CODE.
2-El que va a ser nuevo propietario lo solicita desde su registrante incluyendo el AUTH CODE.
3-Me llega un email para que acepte el traslado.
LISTO
¿Es diferente con Goddady? Resulta que tengo un dominio NO contratado con ellos y el que va a ser el nuevo titular ha solicitado desde allí registrarlo.

No se si el que lo ha solicitado lo ha hecho mal o que, pero me ha llegado un email de goddady con el siguiente contenido que parece indicar que YO quiero trasladar el dominios a MI PROPIA CUENTA de godaddy.
¿Algun alma caritativa que me pueda aclarar el asunto?

Dear xxxx xxxx,

GoDaddy.com, Inc. received a request on 7/5/2010 for us to become the new registrar of record.

You have received this message because you are listed as the Registered Name Holder or Administrative contact for this domain name in the WHOIS database.

Lo he hecho muchas veces, aunque para serte sincero no recuerdo el proceso deberia ser bastante simple.

Por lo que dice en el email:

If you are not the Account Holder, or you are transferring the domain to a new owner, please forward this email to the appropriate Account Holder so that they may complete the transfer process.

Reenviaselo al nuevo titular y que el inicie la transferencia desde su cuenta con el Transaction ID + Security Code, tendria que funcionar.

La otra es que te lo lleves a tu cuenta en GorDaddy y luego le hagas un push.Shut Up !! Shut the hell up ! There's an Artist on stage !! UuUhh, yakalkiu kutulu, yakatomi pakatu, yakatoshi palaka, miu miuli miu yakatoshi kalaka !
