porygon 2 evolves to porygon z i think, I'm not sure
Nope, Pokémon who evolve via trading them will not evolve if you migrate them into Pokémon Diamond, Pearl or Platinum.
You need to evolve Kadabra. By trading your kadabra it will evolve.
Give porygon an upgrade and trade it it evolve it. And of course you have to trade it back. Try this in Pokémon go!
An upgrade is the item you nedd Porygon to hold. Trade it, and it will evolve to Porygon-2. Afterwards, the Dubious Disc is used for evolving Porygon-2 to Porygon-Z in the same way.
Level: Onix Evolves By Trading.
You get it from professor oak it allows one rare Pokemon to evolve. And the answer before this was the real life type of upgrade :P
sorry dude hope you have a friend with a D.S because you can only get it to evolve by trading it
This item can be found in the game it can be used to evolve a Porygon to Porygon2 by trading it to someone.

Rhyperior doesn't evolve, but you can evolve a Rhydon into one by trading it while its holding protector
You can use Upgrade to evolve your Porygon into Porygon 2. To do this. Make your Porygon hold the Upgrade in a trade. (This will only work if trading it to a G/S or newer game.)
You need to train/evolve Abra/Kadabra or you can get it by trading with a friend or over WFC.
