== Upgrade to CentOS 7 ==

'''WARNING''': [https://wiki.centos.org/TipsAndTricks/CentOSUpgradeTool]
DO NOT USE this tool. Warning: use of this tool is currently BROKEN as several system-critical
packages are of a higher version number in CentOS 6.7 than they are in CentOS 7 so those do not
get upgraded correctly. This renders yum and several other system tools non-functional.

Also: [https://shaunfreeman.name/blog/upgrading-centos-6-5-to-centos-7-2]
CentOS 6.6 fails now with the upgrade with error "Downloading failed: invalid data in
.treeinfo: No section: 'checksums'" so this is also broken on CentOS 6.6 now and can ONLY be
done on CentOS 6.5.

Install pre-upgrade assistant:
$ sudo yum install preupgrade-assistant preupgrade-assistant-contents

Install upgrade tool:
$ sudo yum install redhat-upgrade-tool

List upgrade options:
$ sudo preupg -l
CentOS6_7

Check upgrade:
$ sudo preupg
$ sudo preupg -s CentOS6_7

Fix issues.

Import CentOS-7 RPM key:
$ sudo rpm --import http://mirror.centos.org/centos/7/os/x86_64/RPM-GPG-KEY-CentOS-7

Do upgrade:
$ sudo /usr/bin/redhat-upgrade-tool-cli --network 7 --instrepo=http://mirror.centos.org/centos/7/os/x86_64

Erase the existing version of openscap (I had openscap 1.2) and install openscap-1.0.8-1.0.1 from http://dev.centos.org/centos/6/upg and redo the upgrade.

yum erase openscap
yum install http://dev.centos.org/centos/6/upg/x86_64/Packages/openscap-1.0.8-1.0.1.el6.centos.x86_64.rpm
yum install redhat-upgrade-tool preupgrade-assistant-contents

Downloading failed: invalid data in treeinfo: No option 'upgrade' in section: 'images-x86_64'

According to the CentOS Upgrade Tool web page, the tool is currently broken:

https://wiki.centos.org/TipsAndTricks/CentOSUpgradeTool

Therefore the choices are to stay with CentOS 6 (supported till 2020), or backup all your data and do a clean CentOS 7 install then restore your data.
