I have done some FC5 to FC6 upgrades

2. Install the fedora-release for Fedora Core 6. Use the rpm

rpm -Uhv

PMS/fedora-release-6-4.noarch.rpm

a-release-notes-6-3.noarch.rpm
3. Run the yum update: yum -y update. At this point I had to remove
a few packages to get past dependency issues they weren't important
and I just added them back after the update.
I even did a FC7 to FC8 that way. I was wondering if it would be better to do
a
yum upgrade
instead.
I do not know what the --obsoletes really does.
Here's my understanding. "yum update" only replaces a package with a
newer one of the same name. However, sometimes Fedora renames,
combines, or otherwise rearranges packages in such a way that in the
newer distribution, the content you have installed is now found in a
package with a different name. The --obsoletes option makes yum do the
right thing in these cases using the "Obsoletes" information in the new
package. I always use "yum upgrade" in preference to "yum update" to
handle package rearrangements; I don't know of any disadvantages of "yum
upgrade".
