I have two existing site I need to do is transfer the domain name from XYZ .com to XYZ .co. nz. any body please help? I am associated with GoDaddy.
If it's just the domains you need to transfer, first unlock the domain name through GoDaddy. Then request an authorization code. Next, go to the new registrar, select their option to "transfer domain name", purchase that option, and then you should be asked for an authorization code. Input the code GoDaddy email you and that should be it.
If you are associated with Godaddy it won't be too tough for you. It is a long process, I suggest you to read this article. Here you will find step by step procedure of transferring your domain name http://www.smallbusinesswebdesigns.net.au/domain-name-transfers.html
If I understand your questions correctly, you are asking to change the domain of your website from .com to .co.nz so for that you need to do much changes. Are you using WordPress? Or you are using simple website without database?
There is slight difference between registrars, you need to check with your registrar and look out necessary functions/areas/buttonsd to click in your domain control panel. Generally here are the steps/procedures:- Purchase and request domain transfer at the new registrar. Request authorization code at current registrar. Authorization code received from current registrar. Begin the transfer from the new registrar using the authorization code. Email Notification from current registrar. Domain Transfer completed to new registrar.
