[Snort-openappid] Configuration Problem

I did everything but delete the Snort binary and configuration 
directory. But I don't understand deleting the configuration directory. 
That's where all my configuration modifications are kept. Do I really 
need to re-enter all my configuration data? Please clarify.

Thanks for the help.
