Hi,

im trying to upgrade from fedora 9 to fedora 15 following the wiki at Upgrading Fedora using yum - FedoraProject

yum is telling me "Command line error: no such option: --releasever" while trying to sudo yum --releasever=15 --disableplugin=presto distro-sync

any advice of upgradeing fedora without a contained reinstall would be helpful
