Have 2 month P2V and am selling tonite to get a Plus. Can I transfer warranty to him ?

It doesn't say you can't, but it doesn't say you can either.
You will need to give the new owner your original receipt, as that's the first thing DJI will want to see.  

I sent in a zenmuse that I got used and it was less then a year old and I got the original receipt and that was ok for them.

Thanks folks
