How to uninstall netbackup 7.5.0.6 server software on the new server

We in the process of hardware refresh.  I would like to know how to uninstall netbackup server software installed on the new windows 2008.  This server is not yet in the production but i have configured robot and tape using IBM System Storage TS3100 tape library on this server for testing. The installation path is different from the old server and i need to unistall and re-install the netbackup server software due to the installation path issue.  According to Article ID: TECH77447 - installation path must be the same with the old serve.  Please help.

Thanks!
