Use the following command to remove all old services that are going to be replaced by the 10.1.2 product:
<BASEDIR>
/smarts/bin/sm_service remove
<service name>
For UNIX, you need to point the product to the new 10.1.2 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 10.1.2 services, and place it in the 10.1.2 /etc/init.d directory.
