If you actually mean "upgrade", Fedora will not erase any of your 
existing data. The installer should offer to either install or upgrade 
your existing system, and if you choose upgrade at this point, it 
uprades the set of packages that you already have installed.

If it says "do you want me to initialize the drive" - this is a bug - do 
_not_ initialize the drive! This would erase all information. Info at:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=236743

For the clean "-ish" install - remember your user account folder could 
contain incompatible settings, when you get to the installer screen 
above, choose install, then in the partitioning screen there is a 
drop-down with 4 options:
- erase all and use full disk
- erase linux partitions and use full disk
- {forgotten}
- custom
You need to choose custom.

On the disk layout screen, you select each of your partitions, edit, and 
set only the mount point to where you want the partition mounted {eg 
/home for the /home partition}. For LVM lv's you click edit, select the 
individual item, then edit again.

To make the install "clean", set the partition that is for / to be 
formatted.

Review your changes in the list at the bottom of the page, then double 
confirm the request to format {only} the / partition after you click next.
