how to remove pgi cleanly

Hi:
As the topic says, how to remove the pgi cleanly?
I have installed it to /home/ww/App, however I want to put it to /home/ww/App/pgi, so I want to remove it and reinstall it.
How to do ?

Maven,

cd $PGI; rm -rf * will completely remove the installation, and
any other installations of previous releases.

If you want to remove only the 10.3 release,
cd $PGI/linux86 ; rm rm 10.3 2010
cd $PGI/linux86-64 ; rm -rf 10.3 2010

should do it.
