Troubleshooting license type conversion

Windows activation

A license type conversion contains multiple steps. In some cases, when you convert Windows Server instances from BYOL to license included, the billing products on an instance are successfully updated. However, the KMS server might not switch to the AWS KMS server.

To remediate this issue, follow the steps in Why did Windows activation fail on my EC2 Windows instance? to activate Windows either with the Systems Manager AWSSupport-ActivateWindowsWithAmazonLicense Automation runbook, or log in to the instance and manually make the switch to the AWS KMS server.

Instance [instance] is launched from an Amazon owned AMI. Provide an instance launched originally from a BYOL AMI.

You must launch your Amazon EC2 Windows instance from an AMI that you have imported to perform a license type conversion to Bring Your Own License model (BYOL). Instances originally launched from an Amazon-owned AMI aren't eligible for license type conversion to BYOL. For more information, see Conversion prerequisites.

Failed to validate that instance [instance] was launched from a BYOL AMI. Ensure that the SSM Agent is running on your instance.

In order for the license type conversion to succeed, your instance must first have been online and managed by Systems Manager to have its inventory collected. The AWS Systems Manager Agent (SSM Agent) will gather inventory from your instance, which includes details about the operating system. For more information, see Checking SSM Agent status and starting the agent and Troubleshooting SSM Agent in the AWS Systems Manager User Guide.

An error occurred (InvalidParameterValueException) when calling the CreateLicenseConversionTaskForResource operation: ResourceId - [instance] is in an invalid state for changing license type.

To perform a license type conversion, the target instance must be in the stopped state. For more information, see Conversion prerequisites and Troubleshoot stopping your instance in the Amazon Elastic Compute Cloud User Guide.

EC2 instance [instance] failed to stop. Ensure that you have permissions for EC2 StopInstances.

You must have permissions to perform the StopInstances EC2 API action on the target instance. Also, If stop protection is enabled on the target instance, the conversion process will fail. For more information, see Disable stop protection for a running or stopped instance in the Amazon Elastic Compute Cloud User Guide.
