# Deregistering managed nodes in a hybrid and multicloud environment
<a name="fleet-manager-deregister-hybrid-nodes"></a>

If you no longer want to manage an on-premises server, edge device, or virtual machine (VM) by using AWS Systems Manager, then you can deregister it. Deregistering a hybrid-activated node removes it from the list of managed nodes in Systems Manager. AWS Systems Manager Agent (SSM Agent) running on the hybrid-activated node won't be able to refresh its authorization token because it's no longer registered. SSM Agent hibernates and reduce its ping frequency to Systems Manager in the cloud to once per hour. Systems Manager stores the command history for a deregistered managed node for 30 days.

**Note**  
You can reregister an on-premises server, edge device, or VM using the same activation code and ID as long as you haven't reached the instance limit for the designated activation code and ID. You can verify the instance limit in the console by choosing **Node tools**, and then choose **Hybrid activations**. If the value of **Registered instances** is less than **Registration limit**, you can reregister a machine using the same activation code and ID. If it's greater, you must use a different activation code and ID.

The following procedure describes how to deregister a hybrid-activated node by using the Systems Manager console. For information about how to do this by using the AWS Command Line Interface, see [deregister-managed-instance](https://docs.aws.amazon.com/cli/latest/reference/ssm/deregister-managed-instance.html).
