Chapter 3. Upgrading from RHEL 6.10 to RHEL 7.9
The in-place upgrade from RHEL 6 to RHEL 7 consists of two major stages, a pre-upgrade assessment of the system, and the actual in-place upgrade:
- In the pre-upgrade phase, the Preupgrade Assistant collects information from the system, analyzes it, and suggests possible corrective actions. The Preupgrade Assistant does not make any changes to your system.
- In the in-place upgrade phase, the Red Hat Upgrade Tool installs RHEL 7 packages and adjusts basic configuration where possible.
To perform an in-place upgrade from RHEL 6 to RHEL 7:
-
Assess the upgradability of your system using the Preupgrade Assistant, and fix problems identified in the report before you proceed with the upgrade. For detailed instructions, see the Assessing upgrade suitability section in the
Upgrading from RHEL 6 to RHEL 7documentation. -
Use the Red Hat Upgrade Tool to upgrade to RHEL 7.9. For a detailed procedure, see the Upgrading your system from RHEL 6 to RHEL 7 section in the
Upgrading from RHEL 6 to RHEL 7documentation.
