第3章 Manually upgrading using the roxctl CLI
You can upgrade to the latest version of Red Hat Advanced Cluster Security for Kubernetes (RHACS) from a supported older version.
重要
-
You need to perform the manual upgrade procedure only if you used the
roxctlCLI to install RHACS. - There are manual steps for each version upgrade that must be followed, for example, from version 3.74 to version 4.0, and from version 4.0 to version 4.1. Therefore, Red Hat recommends upgrading first from 3.74 to 4.0, then from 4.0 to 4.1, then 4.1 to 4.2, until the selected version is installed. For full functionality, Red Hat recommends upgrading to the most recent version.
- Upgrading to RHACS 4.8 includes an upgrade to PostgreSQL 15 and it requires additional free space on your disk. Before starting the upgrade, ensure you have enough free disk space, ideally almost double the size of your existing database.
To upgrade RHACS to the latest version, perform the following steps:
3.1. Backing up the Central database
