## Description

* * *

The performance of the `migrateLwm2mDevices` operation has been improved. New command line arguments have been introduced with the operation. A list of legacy LWM2M devices can be specified directly from the shell command. Moreover, the migration of the LWM2M client registration objects can be skipped by using an argument.

For details, refer to [Migration of the LWM2M devices](https://community.cumulocity.com/device-integration/lwm2m/#migration-of-the-lwm2m-devices). [DM-1866]
