According to the FAQ (of NEW STEINBERG LICENSING), users who update to Cubase 12 (which is the first Cubase version to use this new licensing system) will not have the option of using the eLicenser for that version (i.e. Cubase 12). This means that, after I update, I can continue to use the USB eLicenser to run Cubase 11?
Yes ,you can use C11 , it just gets marked on the elincer that you have used C11 to update to C12 so if you sell the dongle it can not be used to update/upgrade
