Upgrading the System

You can upgrade the system to a later version.

Common upgrade scenarios include:

The old version has functionality and security issues. You need to upgrade the version to fix the issues.
You need to upgrade to a new version to use new functions.

To perform upgrade in the two-node HA scenario, choose System Management > HA Management, disable data synchronization, disable HA on standby server B (in dual-active mode, disable HA on either of the servers), and upgrade server B. After the upgrade is successful, enable HA on server B, disable HA on server A, and then upgrade server A. After the upgrade is complete, enable HA on server A and then enable data synchronization. This step minimizes the impact on services during the HA upgrade.

Prerequisites

If the cryptographic algorithm or key is updated in the new version, direct upgrade may cause data decryption errors. Before the upgrade, you are advised to decrypt all tables.

Before the upgrade, you are advised to manually back up the system configuration. For details, see Backing Up and Restoring Configurations.
