How can I transfer my shiny rayquaza to my y copy or oras copies besides using poke transporter or Pokemon bank?

I have a legit shiny rayquaza That was shiny restarted and was a gift from a freind. it was transferred multiple times without a problem through the generations. But now in poke transporter it says my rayquaza is a problematic Pokemon and I can’t figure out why. It was legitimately trained to lvl 100, its move set is completely legit yet Pokemon transporter say its problematic, my event genesect that was obtained from me pre ordering white 2 transfered With no problem at all. also my AR salamence was transfred to gen 6 with no problem at all, although it wasn’t shiny its IVS were perfect. If you can tell me any way to fix this problem or tell me another way to transfer it to Oras please do.

Basically, there’s no other way.

If you wish to transfer your Rayquaza from whichever game you have you must do it that order.
