Now that we've got c7 mostly finalized we're starting to look at the upgrade tool. There are several moving pieces for the upgrade tool that will need some patching to work properly.
For anyone who's interesting in taking a dive into the code and helping out, we have some first-run binaries located at http://dev.centos.org/centos/6/upg/ with the source living on git.centos.org
These binaries will most likely not work, but they should provide a decent starting point for testing and debugging.
We do not consider the upgrade tool to be a blocker for c7, so if someone would like to take a swing at the patches required to make this work while we put the finishing touches on getting c7 out the door, it would be greatly appreciated.

for the sake of completeness: looks like all the docs for the inplace upgrade are actually behind a paywall of sorts. so we are going to need to figure this out ourselves.
its been mentioned that this toolset draws from the fedup process - so people familiar with that might be able to help ?

feedback on irc today says that this process just-works. Has anyone else been able to test it ?

I 've been playing around with the preupgrade-assistant packages + sources but it doesn't work for me. I haven't tried an actual migration with redhat-upgrade-tool, though.

I have tried to upgrade an installation of CentOS 6.5 to 7.0, using:
sudo redhat-upgrade-tool --force --iso=/home/lrineau/CentOS-7.0-1406-x86_64-Everything/CentOS-7.0-1406-x86_64-Everything.iso
I have to use --force, because I did run preupg just before, but redhat-upgrade-tool tells me I did not.
My / and /boot and on sort RAID1 partitions (with mdadm). After reboot on the upgrade image, dracut says:
[ 189.272697] localhost dracut-initqueue[476]: Warning: Could not boot. [ 189.333232] localhost dracut-initqueue[476]: Warning: /dev/disk/by-uuid/7605c90b-ab65-4165-94d2-94b91d23a5d8 does not exist
The corresponding disk is the / on RAID1.
I have tried to add "rd.md=1" as option on the kernel line, in grub, but during the boot to the upgrade image, the log says:
[ 3.272702] localhost dracut-pre-trigger[369]: rd.md=0: removing MD RAID activation
and indeed my RAID partitions are not detected. In the dracut emergency shell, mdadm is able to assemble my RAID with: `mdadm --assemble --scan`, but I do not know how to work around that issue.
Hello, I did a minimal install in Virtualbox for Centos 6 and tried to upgrade using the upgrade tools, from centos's repo[1]. But this tends to fail[2]. preupg --list comes up blank. After this I directly proceeded to use redhat-upgrade-tool, as it turns out I need to use --force since preupg failed. The exact commend used is "redhat-upgrade-tool --force --network 7.0 --instrepo http://mirror.centos.org/centos-7/7/os/x86_64/" This works, I encountered errors like[3], but after installing the CentOS 7 keys manually everything worked out. In the end I had a bootable and upgraded CentOS 7 box.
Cheers, Gaurav

Thanks for the feedback .. now lets see if we can get some smart people to help us fix the pre-update tool :)
