az iot hub state import

Experimental

Command group 'iot hub state' is experimental and under development. Reference and support levels: https://aka.ms/CLI_refstatus

Import a Hub state from a file to an IoT Hub.

If the arm aspect is specified, the hub will be created if it does not exist.

By default, the imported state will include: arm template for hub, hub configurations (including ADM configurations and edge deployments), device information (including device identites, device twins, module identities and module twins).

For imported endpoints with system assigned identity authentication, the specified hub must have the correct permissions. Otherwise the command will fail.

Private endpoints will be ignored in the import process.

For more information, see aka.ms/aziotcli-iot-hub-state.

az iot hub state import --state-file
                        [--aspects {arm, configurations, devices}]

Examples

Import the supported state from the specified file to the specified hub.

az iot hub state import -n {iothub_name} -f {state_filename}

Import the supported state from the specified file to the specified hub, overwriting the previous state of the hub. All certificates, configurations, and devices will be deleted before the new state is uploaded.

az iot hub state import -n {iothub_name} -f {state_filename} -r

Import only the arm template from the specified file to the specified hub. Note that this will create a new hub if it does not exist. The file may contain the devices and configurations but those will be ignored.

az iot hub state import -n {iothub_name} -g {resource_group} -f {state_filename} --aspects arm

Import only the devices and configurations from the specified file to the specified hub. Note that this will NOT create a new hub if it does not exist and the command will fail. The file may contain the arm template but that will be ignored.

az iot hub state migrate

Experimental

Command group 'iot hub state' is experimental and under development. Reference and support levels: https://aka.ms/CLI_refstatus

Migrate the state of one hub to another hub without saving to a file.

If the arm aspect is specified, the hub will be created if it does not exist.

By default, the migrated state will include: arm template for hub, hub configurations (including ADM configurations and edge deployments), device information (including device identites, device twins, module identities and module twins).

For migrated endpoints with system assigned identity authentication, the specified hub must have the correct permissions. Otherwise the command will fail.
