It is possible to map several domain names or subdomains to a single blog. In this case, you’ll need to choose one domain as the primary. All other domains associated with the blog will still forward to the blog, but the address that appears in your browser’s address bar will always switch to the primary domain. A common use for this functionality occurs when a domain name is frequently misspelled. You might like to own both the correct and the incorrect spellings, but you would want to assure that the correctly spelled name was set as primary.

To set the primary domain for your blog, navigate to Store -> Domains in your admin sidebar, select the radio button beside the domain you wish to set as primary, and then click the “Update Primary Domain” button at the bottom of the list to save the change. The change should occur immediately, though for very recently purchased domain names, there is sometimes a delay of a few hours between the purchase of the domain and its availability.

@OP, you wish to change your hosting primary domain name therefore you are pleased to contact your current provider to make sure the trick is done instead of doing all those stuff manually by your own.
