I would like to ask a question that I was hoping would get answered
in this thread. With physical hardware machines you can boot from an
Install CD and do an upgrade. I doubt a F7 will be able to handle a
FC1 or lower, but I have upgraded very old machines doing steps (RH8
to FC1 to FC3 to FC5 in the past).
I don't have hardware virtualization, so booting an install CD
within a XenU isn't possible. I am wondering if there is a way to
launch an upgrade process similar to what is on the CD, but within a
paravirtualized XenU.
Just forcing an upgrade of the fedora-release, and then doing a 'yum
update' doesn't work well given the packages are being upgraded in the
same context that yum is running. This is one of those things with
I've seen Debian based systems handle better, and is one of the areas
I'd love to see improvements in Fedora.
Always after a couple of tests on my machines at home, I've two dozen
remote upgrades on production servers using yum. RH9->FC1 was a
complete disaster, but every iteration of FC has been better. I have
one server that has gone from FC2->3->4->5->6 all via yum upgrades and
all remotely (I hate that datacenter). This last go around I took 4
other machines from FC4->5->6 with no problems whatsoever. The one
additional step I always take is: 1) force the upgrade of fedora
release, 2) *upgrade yum*, then 3) yum upgrade the rest of the system.
Side-note: My ISP recommends against doing upgrades with RHEL -- I
have customers with RHEL3 and RHEL4 that I want to upgrade to RHEL5,
and I'm told that the only reliable way to do that is to wipe and
re-install RHEL5 and then reconfigure all my software.
It's in your ISP's best interest to err on the side of caution, but I
don't have any personal experience with RHEL, so I'll leave it at that.
