If you're planning to move your site to a new domain, use the Change of Address tool to tell Google about your new URL. This will help us update our index faster and smooth the transition for your users.
Te duci la Webmaster Tools si iti inregistrezi website-ul vechi. Apoi mergi la Site configuration > Change of address. Restul detaliilor le vei gasi acolo.

Presupun ca daca chiar ei ofera un asemenea tool vor face tot posibilul ca tranzitia sa fie cat mai usoara si sa nu pierzi pozitii in SERPs.
