A dialog box will appear to define the source layers and destination layers.

Select a source layer from the list on the left and a destination layer from the list on the right. Click the Add button to save the setting, and repeat this process as many times as needed to transfer objects from multiple source layers to the corresponding destination layers.

Additionally, you can check the option to Purge the source layers after their objects have been transferred to the destination layers.

Press OK and the object layers will be changed as your settings.
