Will Leopard to Snow Leopard upgrade mess up my SSH / VNC setup?

Question

I have an SSH server and Vine server set up on Leopard with public key file in .ssh directory and appropriate settings in the /etc/sshd_config file.Will upgrading to Snow Leopard overwrite this requiring me to set it all up again? And how about the SSH Key Fingerprint - will this be changed by the Snow Leopard upgrade?

It shouldn't but it can't hurt to be careful:

The big question is, where is the physical location of DropBox.  If it is on the same machine it is not a backup.  A backup is a separately stored location. 
Time Machine shouldn't search for a wireless device unless you set it up with a Time Capsule, or connected the drive to an Airport base station which was using drive sharing at the time that Time Capsule was connected.  Time Capsules, are special wireless (WiFi, Airport) routers that include hard drives.  See my link on my user tip above (2455) which includes information about backing up.  Time Machine backups to external hard drives are back ups that are most usable if they are backups from older Macs or the same aged Macs as the ones they are being restored to.    The only problem is if the old Mac was pre-2006 in age.  Then you may need to cherry pick data out of the Time Machine backup to an Intel Mac.  Also older applications may not transfer if the were initally designed to work on pre-2006 Macs.
