Chapter 3. Upgrading from RHEL 6.10 to RHEL 7.6
This section describes the key steps for an in-place upgrade from RHEL 6 to RHEL 7.
The in-place upgrade 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 Step 2: Perform the system assessment in the
