When you sign up for Google Apps, you give the name of the Internet domain for your organization. This domain name becomes the primary domain associated with your Google Apps account. As the account administrator, you use the primary domain name to sign into the Google Admin console for your account.
You can associate additional domain names with your Google Apps account, as separate domains or as domain aliases for your primary domain. However, at this time you can't change which domain is your primary domain except when you upgrade from a trial mygbiz.com domain to a custom domain. Otherwise, your only option for a new primary domain is to create a new account and migrate your data to the new account.
To create a new account and migrate your data:
- Create a new account with the new primary domain.
Sign up for and create a Google Apps account for your new domain name at http://www.google.com/a/.
The domain name must not be associated with any existing Google Apps account. If it is associated with an existing account, you must remove it before creating the new account.
- Migrate your data to the new account.
Use one of the email migration options to transfer mail from accounts in your old domain to your new domain. Export any documents, spreadsheets, and presentations you would like to retain and upload them into your new domain, or share them with a user account in the new domain and copy them.
Note: We do not offer migration options for Google Sites. Instead we recommend that you use one of our alternative methods to perform that function:
- Create a back up for the content in Google Drive and recreate the site once you register with the new domain name.
- Add the new domain admin as owner of the site and then copy it inside of the new domain.
- For those using the Sites API, you can go here for the migration options that are available to you: http://code.google.com/p/google-sites-liberation/
- Delete your old account.
Once all of your data has been transferred or backed up, delete the Google Apps account for your old domain. It takes 24 hours for the account to be removed from our system.
- (Optional) Add the previous primary domain to your new Google Apps account.
If you want to retain the old primary domain as a non-primary domain with access to your Google Apps functionality, add it to the new account.
