If you downgrade your Nodegrid device to a version below 6.0.10 and if the device is enrolled in a non-US ZPE Cloud instansce, such as the EU ZPE Cloud instance, the device will lose its access to the ZPE Cloud. Therefore, you must unenroll the device from ZPE Cloud and reenroll it to restore its access to the ZPE Cloud.

Follow these steps to unenroll the device and downgrade the device to a version lower than 6.0.10. Before performing these steps make sure that you have direct access to the Nodegrid device:

Log in to the ZPE Cloud Web UI.
Go to Devices :: Enrolled.
In the table, locate the device you want to unenroll and select the checkbox(es).
Click MENU (expands dialog).
On the left panel, click MOVE TO AVAILABLE.
Click Move to confirm unenrolling the device. The selected device is moved to the AVAILABLE tab.
Click AVAILABLE.
In the table, locate the device and select the checkbox(es).
Click Remove.
Type confirmation text.
Click OK.
Access the device via terminal as root.
Execute the following command to remove all the device instances from ZPE Cloud. You must perform this step to ensure that your Nodegrid device complete instance is removed from ZPE Cloud. xt
```
zpe_cloud_enroll  -u https://zpecloud.eu --realm zpe --enroll-clean
```
Downgrade the device to the older version.
Register the device back to EU ZPE Cloud. For registration steps, see Sign up for ZPE Cloud section.

Execute the following command to enroll device back to the ZPE Cloud:
