Post-Upgrade Checks and Handling

After the upgrade is complete, clear the browser cache, restore the HA policy as needed, and check service status and version information.

Clear the browser cache manually.
To ensure that new features work properly, log in to the UI management interface after the upgrade is complete and press Ctrl+F5 or Ctrl+Shift+R to clear the browser cache manually.
Enable the HA policy as needed.
If you disabled the global switch for VM high availability before the upgrade, go to Reliability > HA Policy and enable the HA policy after the upgrade is complete and the environment is running properly.

Check the management node service status and version information.

[root@localhost ~]# zstack-ctl status
[root@localhost ~]# zstack-ctl ui_status
[root@localhost ~]# cat /etc/redhat-release

If you upgraded a management node HA environment, check the management node HA service status and version information.
```
[root@localhost ~]# zsha2 status
[root@localhost ~]# zsha2 version
```
