Flash Media Server Update Process

Hi all,

I currently have Flash Media Server 3.5.0 installed and it has been running since 2009.  It has been running for so long without issues I kind of forgot about it.  Now i see there is an update to 3.5.7.  I downloaded it but when I ran the installer it warned me that all my configuration settings may be lost.  I tried to find some info on the best procedures to follow to perform the update but was unable to find much.  I really do not want to lose my settings.  I looked in the FMS admin console but i did not see any option to backup the current settings. 

What is the best way to proceed with this update without losing your settings or negatively impacting the media server?
