红帽全球峰会第 1 章 支持的升级路径
目前，您可以执行从 RHEL 8 原位升级到以下目标 RHEL 9 次版本：
| 系统配置 | 源操作系统版本 | 目标操作系统版本 |
| SAP HANA | RHEL 8.10 | RHEL 9.4 |
| RHEL 8.10 | RHEL 9.6 | |
| SAP NetWeaver 和其他 SAP 应用程序 | RHEL 8.10 | RHEL 9.4 |
| RHEL 8.10 | RHEL 9.6 |
SAP HANA 由 SAP 为 RHEL 次版本进行验证，这些次版本接收软件包更新超过 6 个月。SAP NetWeaver 由 SAP 针对每个主要 RHEL 版本进行验证。支持的原位升级路径与从 RHEL 8 升级到 RHEL 9 文档中所述相同。
托管 SAP HANA 和其他 SAP 应用程序的升级非常类似。Section 4 中描述了某些偏差。升级 SAP NetWeaver 系统。对于同时安装 SAP HANA 和 SAP NetWeaver 的系统，SAP HANA 的限制适用。
