Perform an Online Upgrade to Workspace ONE Access 20.10

If your existing 20.10 virtual appliance has Internet connectivity, you can upgrade the appliance online.

Prerequisites

The prerequisites listed in Prerequisites for a Workspace ONE Access Online Upgrade are verified.
Verify that the virtual appliance is powered on and functioning.

Run the following updatemgr.hzn command.

/usr/local/horizon/update/updatemgr.hzn updateinstaller

Run the following command to check that an online upgrade exists.
```
/usr/local/horizon/update/updatemgr.hzn check
```
Enter y to proceed with the upgrade of the Workspace ONE Access service or enter n to exit the upgrade.
Run the updatemgr.hzn check command again to verify that a newer update does not exist.
```
/usr/local/horizon/update/updatemgr.hzn check
```
Restart the virtual appliance.
reboot
Check the version of the upgraded appliance.
```
vamicli version --appliance
```
The new version is displayed.
After you upgrade all the nodes in your Workspace ONE Access deployment, use the diagnostics dashboard to monitor system information health.
1. Log in to the Workspace ONE Access console.
2. Select Dashboard > System Diagnostics Dashboard.
3. If your deployment consists of more than one Workspace ONE Access appliance, select the appliance you want to monitor.
4. Check the status of the various services.
  For example, to check the health of the Elasticsearch service, review the Integrated Components section and confirm that the values for the Elasticsearch items are as expected. Therefore, the value for Elasticsearch - Health is Green, the information about the cluster nodes is accurate, and so on.

The upgrade is complete.
