Chapter 1. Supported upgrade paths
The in-place upgrade replaces the RHEL 8 operating system on your system with a RHEL 9 version.
It is not possible to perform an in-place upgrade directly from RHEL 7 to RHEL 9. However, you can perform an in-place upgrade from RHEL 7 to RHEL 8 and then perform a second in-place upgrade to RHEL 9. For more information, see Upgrading from RHEL 7 to RHEL 8.
Currently, it is possible to perform an in-place upgrade from the following source RHEL 8 minor versions to the following target RHEL 9 minor versions:
| System configuration | Source OS version | Target OS version |
|---|---|---|
| RHEL | RHEL 8.8 | RHEL 9.2 |
| RHEL 8.10 | RHEL 9.4 | |
| RHEL 8.10 | RHEL 9.5 | |
| RHEL with SAP HANA | RHEL 8.8 | RHEL 9.2 |
| RHEL 8.10 | RHEL 9.4 |
For more information about supported upgrade paths, see Supported in-place upgrade paths for Red Hat Enterprise Linux and the In-place upgrade Support Policy.
