Yes - using force, the old will be overwritten anyway, so it is not needed uninstall the other, newer before as the file name is always identical. Do you remember my CPUSE Deployment Agent install script ? You will have to use the procedure from there (or directly from sk92449) to stop and restart DA.
Only in theory you could use rpm:
# $DADIR/bin/dastop
# rpm -e CPda-00-00.i386.rpm
...but this will give you an error: package CPda-00-00.i386.rpm not installed
