From Fedora Project Wiki
This describes the steps necessary to rename a project in Fedora Hosted.
Rename the Trac instance
cd /srv/web/trac/projects mv oldname newname cd newname/conf sed -i -e 's/oldname/newname/' trac.ini cd .. sudo -u apache trac-admin . resync
Rename the git / svn / hg / ... directory
cd /git mv oldname.git newname.git
Rename any old releases directories
cd /srv/web/releases/o/l/oldname (somehow, the newname releases dir gets created; if there were old releases, move them to the new location).
Rename the group in FAS
