How do I update from version 6.01 to current version 6.08

I have KTS Bee version 6.01 and would like to update it to the current version 6.08 without losing all my work.  How do I update my old version?  I have downloaded the newest version 6.08, yet can not identify which folder(s) to do the update with.  Any help?  Thank You! 

I have an added image of the breakdown of my website tree using FTP. 

 

And I have included an image of my control panel tree/breakdown. 

 

First of all make a backup of your current site. Then download params.ini from kbee config folder and save it on your computer. Delete Kbee from Kunena and install latest version. Then upload saved params.ini to config folder.
Or unpack zip file, delete /config/params.ini and upload all files with ftp to kbee folder.

That worked!  Yet, the primary problem was where was the folder for NTS-Kbee.  I downloaded the entire website by FTP to the local computer and did a search for the params.ini file and by doing so I found the folder where NTS-KBee is located!  I then proceeded to remove the params.ini from the downloaded updated version (6.08)  and inserted the old params.ini into it and then FTP to the appropriate folder.  That was the 2nd option you mentioned.  Thanks for the help!  Glad it worked!
