红帽全球峰会第 1 章 Supported upgrade paths
The in-place upgrade replaces the RHEL 9 operating system on your system with a RHEL 10 version.
You can perform the in-place upgrade only from one major RHEL version to the next consecutive one, for example, RHEL 8 to RHEL 9 or RHEL 9 to RHEL 10. If you want to upgrade a system across multiple versions, such as from RHEL 8 to RHEL 10, you must perform multiple in-place upgrades to reach your target version.
Currently, you can perform an in-place upgrade from the following source RHEL 9 minor versions to the following target RHEL 10 minor versions:
| System configuration | Source OS version | Target OS version |
|---|---|---|
| RHEL | RHEL 9.6 | RHEL 10.0 (EUS) |
| RHEL | RHEL 9.7 | RHEL 10.1 |
In-place upgrade paths in this table are guaranteed only for systems that use Red Hat Subscription Manager (RHSM). For Pay-As-You-Go (PAYG) RHEL systems that use Red Hat Update Infrastructure (RHUI), only the latest available upgrade path is supported. Note that this does not impact RHEL systems with SAP HANA installed.
