The 
Remove
                     Existing Configuration feature of the 
SAS Deployment Manager provides an automated way to remove one or more products of a SAS 9.4 configuration
                  from your environment. With this feature, you can remove the configurations of all
                  SAS products or just selected products from a machine.
                  
               
 
               
               When removing a product configuration, you must first determine the product’s dependencies.
                  If you remove a product configuration that another product depends on, then the dependent
                  product is not able to function. Therefore, when you remove a product’s configuration,
                  the SAS Deployment Manager requires that you also remove the configurations of any
                  dependent products.
                  
               
               
               Note: Starting with release 7.3,
                  SAS Visual Analytics provides sample objects. For this reason, when
                  unconfiguring SAS Visual Analytics, the SAS Content Server must be
                  running.
