To issue a transfer code (Child KP code) you must acces the profile of the child leaving school / kindergarten. On the left is a pink "Deactivate account" button.

When pressed, the child will be removed from the group in which he was and will be placed in the "Inactive" category. Instead of the pink button now appears the transfer code that will be used by the new administrator to add the child to his / her new school / kindergarten.
