A. You can see the price to change the domain name on the
products page in the software addons section. You can purchase a domain transfer through the shopping cart on the page for your site inside of the WMT client admin. Transferring a domain is a "Task", not a support request, so you are charged a one time for each transfer, you will not consume support credits. However, there may be side affects from the transfer where things links still point to the old domain and/or places where the old name still appears. Time spent fixing these issues are charged as a support request and not included in the set price. We do not check for such issues and you would need to send us a list of issues in a support request for us to fix them. Most transfers with just 1 or 2 pages do not have this issue, but if there is an issue it normally costs less then $25 worth of credits to fix all of the pages.
Transferring the domain take only a couple of hours and is usually done at night as your site will be down during the process. Our software designer will transfer your site. It may take 1-3 days for your task to be worked on (depending on the current work load). You will be contacted when it is time to point your new domain to our servers.
