Dongle Durability

I understand that one can perhaps not do this completely on one’s own (requiring perhaps a support request) , but I have been given to understand that this transfer of licences from dongle to dongle is possible over the’ My Steinberg’ site.
Am I wrong - or what is meant by …sort things out…?
Please explain, as I intend to buy Wave lab but put the license on my Cubase dongle, and keep the one received with Wave lab in reserve.
