Rollback Notes
Rollback Constraints
- After the upgrade is performed, the HA version remains unchanged before the upgrade takes effect. You do not need to roll back the HA version.
- After the upgrade is performed, if a failure occurs during the process of making the upgrade take effect, the HA system automatically rolls back.
Rollback Guidelines
If the upgrade fails and the HA version is still the source version, you do not need to perform a rollback. If the following problems occur after the upgrade takes effect, determine whether to perform a rollback:
- A major fault occurred during the upgrade, and cannot be located and rectified within the specified time.
- After the upgrade is complete, the target version functions abnormally.
