Chapter 4. General Updates
In-place upgrade from Red Hat Enterprise Linux 6 to Red Hat Enterprise Linux 7
An in-place upgrade offers a way of upgrading a system to a new major release of Red Hat Enterprise Linux by replacing the existing operating system. To perform an in-place upgrade, use the
Preupgrade Assistant
, a utility that checks the system for upgrade issues before running the actual upgrade, and that also provides additional scripts for the Red Hat Upgrade Tool
. When you have solved all the problems reported by the Preupgrade Assistant
, use the Red Hat Upgrade Tool
to upgrade the system.
For details regarding procedures and supported scenarios, see https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Migration_Planning_Guide/chap-Red_Hat_Enterprise_Linux-Migration_Planning_Guide-Upgrading.html and https://access.redhat.com/solutions/637583.
Note that the
Preupgrade Assistant
and the Red Hat Upgrade Tool
are available in the Red Hat Enterprise Linux 6 Extras channel, see https://access.redhat.com/support/policy/updates/extras. (BZ#1432080)
cloud-init moved to the Base channel
As of Red Hat Enterprise Linux 7.4, the cloud-init package and its dependencies have been moved from the Red Hat Common channel to the Base channel.
Cloud-init
is a tool that handles early initialization of a system using metadata provided by the environment. It is typically used to configure servers booting in a cloud environment, such as OpenStack or Amazon Web Services. Note that the cloud-init package has not been updated since the latest version provided through the Red Hat Common channel. (BZ#1427280)
