Change Main Domain Name On A Multisite

How Do I Change Main Domain Name On A Multisite without having to leave wp and go to php My admin .and change the

wp_options: options named “siteurl” and “home”
wp_sitemeta: the option named “siteurl”
wp_blogs: any entries in the “domains” column that have the old domain name
wp_#_options: Each sub-site will have sets of tables that correspond to the blog_id in the wp_blogs table. You need to go to the wp_#_options table, where # corresponds to the blog_id, and update the “siteurl” and “home” settings in that table.
In order to make these changes, you’ll need to utilize phpmyadmin to edit your database.

i dont want to do that and cause an error between the multisite.. please let me know thanks.. perhaps using the clone tool.. i really just wanna copy one of the sites i created already.. replacing the content of the main domain
