You can still get to CDR/CAR via the services menu in CUCM. That functionality is still there as long as you have CDR enabled on the cluster. What you're referring to is the best way to preserve your CDR files which is to leverage a "Billing Server" where you FTP/SFTP the CDR flat files to an off-box location/application (i.e., 3rd-party CDR tool such as Metropolis, Avotus, etc).
