My understanding is that there is an issue with LVM and since the default 
install of fedora uses LVM upgrading was an issue in yum.  Although I 
have managed to upgrade fedora fc4 -> fc6 through fc5.  Generally it 
needed yum upgrade yum then yum upgrade kernel and then rebooting into 
the new kernel then doing a yum upgrade all.

You will however need to go from fc4 -> fc5 -> fc6.  Debian does do it 
better however fedora is improving with there recent move towards opening 
up rpm then from there yum will improve.

Someone mentioned smart before. I'm not sure if it can be done however 
the benefit with smart is the multi package downloading. While this is 
standard with apt/aptitude it hasn't been implemented with yum for some 
reason.  All in all fedora is a different ditro and in some areas it is 
playing catchup where as in other areas it is quite good.
