Once a client’s account has been migrated to the new platform, all aspects of all domains associated with the account can be managed from an interface called DomainCentral in the client’s control panel.
You can access your client’s DomainCentral interface via your Reseller Console, and you and your client can access it by logging into the client account directly:
http://www.yourwebhosting.com/controlpanel/domaincentral/3.0/
We’ve documented an extensive amount of information about domain management on the new platform in our Knowledgebase. It’s available on yourwebhosting.com, but you’ll need to log in as your client to view it (nearly all pages on yourwebhosting.com are behind login). The same information is available on verio.com (though don’t forget that, for your clients, substitute yourwebhosting.com for verio.com).
