PREFACE

PREFACE

This document describes steps for an in-place upgrade from RHEL 6 to RHEL 7. The supported in-place upgrade path is from RHEL 6.10 to RHEL 7.9. If you are using SAP HANA, follow How do I upgrade from RHEL 6 to RHEL 7 with SAP HANA instead. Note that the upgrade path for RHEL with SAP HANA might differ. The process of upgrading from the latest version of RHEL 6 to the latest version of RHEL 7 consists of the following steps:

1. Check that Red Hat supports the upgrade of your system. See Chapter 1, Planning an upgrade for more information.

2. Prepare your system for the upgrade by installing required repositories and packages and by removing unsupported packages. See Chapter 2, Preparing a RHEL 6 system for the upgrade got more information.

3. Check your system for problems that might affect your upgrade using the Preupgrade Assistant. See Chapter 3, Assessing upgrade suitability for more information.

4. Upgrade your system by running the Red Hat Upgrade Tool. See Chapter 4, Upgrading your system from RHEL 6 to RHEL 7 for more information.
