Upgrade Overview
Updates and maintenance are provided for HCE and the RPM packages, including RPM packages deployed on HCE and those related to security updates for vulnerability fixing. To ensure system security, always install updates in a timely manner.
You can upgrade HCE using either dnf, yum, or OSMT:
- In Linux, you can use dnf or yum to upgrade or roll back RPM packages.
- OSMT is a software tool from Huawei Cloud that you can use to upgrade or roll back HCE and RPM packages. OSMT allows you to customize the upgrade scope and configure scheduled checks and delayed restarts.
Differences between the two methods are described in the following table.
