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.
