Can we Wonder Trading pokemon between generations?

Question

For example, I'm wonder trading some pokemon from Sun & Moon, and in the same time my friend also wonder trading, but he wonder trading from pokemon X & Y.

Is it possible that our trade meet each other in wonder trading?

I've read this but, I don't think it is also true with Wonder Trading?

Answer 1

No, that is not possible. You may use Pokebank from next month to transfer between generations like in the link you posted, but XYORAS wonder trade is separate from SM's.
