Which package name should be use when Fedora 9 release and I upgarde my Fedora 8

[Wong Kwok-hon]

Hello all,

I know some one did a great job that call "preupgrade" that can use a
GUI to upgrade the system from Fedora 7 to 8, Fedora 8 to 9.

I am now in Fedora 8 and would like to upgrade to Fedora 9 when released.
But which package name is used of "preupgrade" ?
Any additional packaged need to install first ?

Thanks!

Best Regards,
