Chapter 5. Upgrading from RHEL 7.9 to RHEL 8

Similarly to the in-place upgrade from RHEL 6 to RHEL 7, the in-place upgrade from RHEL 7 to RHEL 8 consists of two major stages, a pre-upgrade assessment of the system in which the system remains unchanged, and the actual in-place upgrade. In case of a RHEL 7 to RHEL 8 upgrade, both phases are handled by the Leapp utility. Note that RHEL version 7.9 is a prerequisite for upgrading to RHEL 8.

To perform an in-place upgrade from RHEL 7.9 to RHEL 8:

  1. Assess the upgradability of your system and fix reported problems as described in Reviewing the pre-upgrade report of the Upgrading from RHEL 7 to RHEL 8 document.
  2. Upgrade your RHEL 7 system to RHEL 8 per instructions in Performing the upgrade from RHEL 7 to RHEL 8 of the Upgrading from RHEL 7 to RHEL 8 document.
