What happens if a Pokemon traded to another generation has the same OT, ID and Secret ID combo as the previous game?

For example, I trade a Zangoose from Black 2 to Omega Ruby using the PokeBank. The OT (original trainer name), ID and Secret ID on both games are exactly the same, which, under normal circumstances, would have the Zangoose act like a Pokemon I caught on my own, obeying every command and not gaining extra EXP. However, there is a generation gap, the game will say that it came from Unova. Will the Zangoose get the boosted EXP and act as an outsider Pokemon, or will it act like I never transferred it in the first place and obey my every command if I’m missing badges?

This can be asked about any trading between any generation, like gen 1 to gen 2, gen 3 to gen 4, gen 4 to gen 5, etc.

(Yes I know the chances of this happening are slim to none, I’m still curious.)

It will act as a traded Pokemon because of the region difference. Also Pokemon don’t have secret IDs, only trainers. Any difference at all is enough for it to be a traded Pokemon. This is only for 6th gen though. I don’t know about past generations.
