Hi Mariola,
The Edge device relocation feature must be implemented by the Device Builder which is in this case Siemens IPC device builder. The IPC operating system IED-OS 1.12 contains IEDK version 1.12 which enables you to migrate from old IEM-OS to new IEM offerings IEM Virtual, IEM Cloud and IEM Pro and it is supported by the device builder.
See platform docs here about the relocating edge devices.
