[horde] Update Components

[Stefan Stolz]

Hi,

i found nowhere information for this simple question. I think it was  
asked many times befor, but its hard to find something with this  
keywords. Perhaps someone should put the information into the Wiki?

I wanted to update the Kronolith (2.1) component to new version. Now  
is my question: Can i simply put it over the old version, or must i  
delete the old and configure the new again?

Thanks
Stolzi
