Upgrade - Safe?

[Kimmy @ telia.com]

Hi all! Im new to this list, just downloaded the five ISOs via 
bittorrent, and now i got some questions.

I'm currently running FC1, with WWW, FTP and SSH server, is it safe for 
me to just run an Upgrade installation? (or will anything dissapear/be 
damaged/displaced?)

Also, it seems that there's no way of booting from a floppy anymore, and 
since i just got SCSI CD/DVD-ROM players i cannot boot the installation 
CD direct... Can i use the boot disk from FC1?
