As far as I know, F13 did not get a version of preupgrade that is 
capable of upgrading to F17.  Do not attempt to upgrade in one go. 
Upgrade to F16 first, then use preupgrade.

If you don't want to step the ladder in that fashion, look carefully at 
what is required to prepare your system for the upgrade to F17.
