Question on upgrading from fc6 to 7 on ppc.

[Jimmy Bradley]

       I've been running fc6 on my Ibook for some time now. I've tried
doing a network install of fc7 3 times on it, and each time the install
gets to a point and then just hangs up. It hasn't been at the same point
that it keeps stalling out.
       I was wondering, do you think I'd have better luck trying to
upgrade from fc6 to 7 using yum instead?
       Thanks
       Jim
