An in-place upgrade is the recommended and supported way to upgrade your system to the next major version of RHEL.

1.1. How to upgrade from Red Hat Enterprise Linux 6

The Upgrading from RHEL 6 to RHEL 7 guide 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 RHEL 6 to RHEL 7 consists of the following steps:

  1. Check that Red Hat supports the upgrade of your system.
  2. Prepare your system for the upgrade by installing required repositories and packages and by removing unsupported packages.
  3. Check your system for problems that might affect your upgrade using the Preupgrade Assistant.
  4. Upgrade your system by running the Red Hat Upgrade Tool.
