I personally would never do an in place upgrade on a production machine.
 Call it a personal bias.

The versions we have released do not work .. there are updates that need
to be refactored and rolled in.

There are several upgrades to the tool, and I expect there will be
another set shortly before or just after the 6.8 release.

Here are the tools used:

Pre Upgrade Assistant:

Upgrade Tool:


As you can see, there have been several updates since the last time an
update was rolled in (4 updates to the c6 upgrade tool, 6 upgrades to
the preupgrade-assistant.)  The openscap might be OK as is, not 100% sure.

These packages were supposed to be community maintained, but no one has
done the work to try to keep this updated.  I can TRY to do this (but
not for a while), but it would be better if someone from the community
would do it.

Thread concerning the initial tool patches:

NOTE: The patches are scrubbed from the list, but if you have archives
of the email, they are attached to the actual mails.  The are also in
git.centos.org now.

Another thread:


and another:


So, what we need is someone from the community to maintain this.  Is
there anyone who will take a look and refactor the patches and test?
This would be done on the centos-devel mailing list.  If you will
maintain it .. the info is in git.centos.org, format the patches as 'git
am' patches and I will work with you to get them into git and the
packages built.

If we can't get someone, then I will try to do it when I have time, but
it is not something that is a high priority and it has to come after my
other work.  I don't know when I can get to it.
