How to Uninstall or Disable ColdFusion 9?

In May 2012 we moved ColdFusion 9 from a CentOS 5.5 linux server to a Windows 2008 server.  After some research it seemed like we could use the same serial number on the new server and there was a grace period to deactivate CF on the old server.    The move went very smoothly.

On the old server we had 4 or 5 websites using CF and after this move, I disabled or deleted those sites since we weren't using CF on the CentOS server anymore.

Recently I realized that ColdFusion is still installed on the old CentOS server and probably still running even though we're not using it.  To avoid licensing issues I want to uninstall, remove, or disable CF on the old server.

I'm a complete Linux noob and my server admins know nothing about ColdFusion, so I'm here for help.  My skills include logging into root, running 'top' and tailing a log file.  That's about it but I know how to google for help.

I found this thread:

And now I'm paranoid about uninstalling CF9.  I don't have an easy way to restore the whole server if we have a major issue.   So I'm looking for the next-best-thing... how to disable CF9 in Linux so it never runs?  Or how to uninstall it safely?

Thanks in advance for any help I can get,
