I just tried out the upgrade tool to upgrade a server from C6.6 to C7.0. Unfortunately the server doesn't some up any more. Screenshot:

Doesn't get past Welcome to CentOS Linux 7 other than printing something about a dependency cycle.
Will have to look around more tomorrow.

So, the machine finally completed booting after 30-40 minutes or so. However, it is not pretty much unusable apparently because the sssd* packages were not upgraded. Perhaps this is because on el6 sssd version is 1.11.6 (as of Dec 9th) and on el7 the version is still 1.11.2. I would have thought that the upgrade process would have used the equivalent of distro-sync though for such situations (it is what is used in https://fedoraproject.org/wiki/Upgrading_Fedora_using_yum), but maybe something else went wrong.

Actually, I believe the real killer was openldap:
2.4.39-8.el6 -> 2.4.39-3.el7
as this caused many programs, including ssh and python (yum), to try to load libsasl2.so.2 instead of the newly installed libsasl2.so.3. Managed to download rpms with wget and install via rpm.

The redhat-upgrade-tool on RHEL6 reports:

I'd be hard pressed to image many systems without all of these. Especially since yum depends on openldap!
Running the tool again on centos6 I see the same message printed - didn't notice it the first time.

FWIW - I've filed https://bugzilla.redhat.com/show_bug.cgi?id=1173713 to say that the upgrade tool needs to use distro-sync. It's fundamentally broken without it.

With much egg on my face now, it appears that the redhat tools take these issues into account and fix them. See https://bugzilla.redhat.com/show_bug.cgi?id=1174335 for some more details. Looks like the CentOS upgrade tool has a ways to go towards implementing the upstream process.

Ideas as to patches or required changes for this? Have we just not kept up with upstream versions? Admittedly I haven't followed the status of the upgrade tool.

I would definitely like to see this tool maintained.

I think we are one update behind on this tool ... I have to refactor all the updates that do not apply to the new one.
The updates for this are massive and basically when done, we have our own complete version that is significantly different than upstream.
I will try to work on this as my number one priority after maintaining updates until we can get the latest version out.
Thanks, Johnny Hughes
