Import config settings from rt-ac68u onto a rt-ac86u?

Hi

I have an old Asus rt-ac68u wireless router, and want to upgrade to the newer Asus rt-ac86u. Does anyone in this forum know if I can just export the settings from the rt-ac68u and then import them to the rt-ac86u? Or do I have to manually redo the whole configuration on the new rt-ac86u?
