Review your users During your service transition, your Postini users are moved to Google Apps. Both primary addresses and aliases are copied over. To review your users: Sign in to the Google Admin console. Click the Users icon to open the Users page. To review your users within individual organizations—or organizational units (OUs)—click any of the organization links in the right column. For instructions on adding users to an organization, or moving users from one organizational unit to another, see Options for adding users and Move a user to an organizational unit. For instructions and details about user aliases, see Add email aliases and Email aliases. After your service transition, you will have read-only access to your Postini Administration Console, so you can sign in and keep the Postini Admin Console open in a separate browser window as you check your Google settings.
