Hi guys, I know it's a pretty noobish question but I can't find a solution. I have a blog running on an inf0-domain, now i want to change the domain. I want to buy this domain at namecheap, my hoster is dynadot. How can I "exchange" these two domain-names without destroying my google ranking? Do I have to put a nameserver a in the field at namecheap? Because when I do this with the one from dynadot it says: Invalid.
