Use the following command to remove all old services that are going to be replaced by the latest product:

         /smarts/bin/sm_service remove 
         <service name>

For RHEL/CentOS, you need to point the product to the new services that will be installed. Do this by making a copy of /etc/init.d/ic-serviced, change the SMHOME variable to point to the latest services, and place it in the latest /etc/init.d directory.
