When the WFM cluster was configured we have used this command:
Add-SBHost -SBFarmDBConnectionString 'Data Source=SQLWFM;Initial Catalog=SbManagementDB2;Integrated Security=True;Encrypt=False' -RunAsPassword $SBRunAsPassword -EnableFirewallRules $true -Verbose -ExternalBrokerUrl 'sb://wfm.internalra.net';
now we need to change 'wfm.internalra.net' DNS to our new domain 'wfm.ra.net'
What is the process for doing that ?
