# How to Unenroll the Nodegrid devices during Downgrade from ZPE Cloud EU

If you downgrade your Nodegrid device from a version equal or **higher than v6.0.10** to a version **below v****6.0.10** and if the device is enrolled in **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. A compatibility difference between the versions that requires those steps. **The recommendation is always to upgrade to higher versions**.

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:

1. Log in to the ZPE Cloud Web UI.
2. Go to *Devices :: Enrolled*.
3. In the table, locate the device you want to unenroll and select the checkbox(es).
4. Click **MENU** (expands dialog).
5. On the left panel, click **MOVE TO AVAILABLE**.
6. Click **Move** to confirm unenrolling the device. The selected device is moved to the AVAILABLE tab.
7. Click **AVAILABLE**.
8. In the table, locate the device and select the checkbox(es).
9. Click **Remove**.
10. Type confirmation text.
11. Click **OK**.
12. Access the device via terminal as root.
13. 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:ShellShell 

```shell
zpe_cloud_enroll -c <customer-code> -k <enrollment-key> -u https://zpecloud.eu --realm zpe --unenroll
```
14. Downgrade the device to the older version.
15. Execute the following command to enroll device back to the ZPE Cloud:
