Give it an Up-Grade, trade it, and then it will evolve into Porygon-2. If you have a Dubious Disc, too, then give that to your Porygon-2 and trade it again, and it will become a Porygon-Z.
you have to get a porygon, then trade it with an upgrade, then you have to trade porygon2 with a dubious disc, which is found in the team galactic headquarters in veilstone city.
no you need a friend to trade a Pokemon with you than give it back the computer would keep you Pokemon and you wouldn't get it back
Trade Porygon with Up-Grade. This poses three problems. How to get Porygon, how to get an Up-Grade and trading. You can get Porygon in Veilstone City. Go to the house top-right of the Pokemon center. You get an Up-Grade on Route 224 and Eterna Galactic Building. Now you need to get a friend and trade or go onto the GTS.
Attach the Upgrade to a Porygon and trade it to another game. It will evolve into Porygon2 when it arrives in the other game.
He doesn't evolve at a certain level. Somebody has to trade you a Porygon holding an Up-Grade. Or, you trade a porygon with an upgrade.and then trade back.right that instant it evolves into porygon2. then trade porygon2 holding a dubious disc and trade back. it will evolve into porygon-z. I didn't make any mistakes on this. believe me!!!!!!
you have to link trade porygon
you have to have a upgrade and then trade it
you give porygon the upgrade then trade it to get a porygon 2 then you give your porygon 2 another upgrade and trade yet again to get a porygon-z
To evolve Porygon to Porygon2, you will need to have it hold an Upgrade and trade it. You can get Porygon-Z by having Porygon hold a Dubious Disk and trade it.
Just Evolve Porygon(1). And To Evolve Porygon(1),You Must Trade It.
trade while holding up grade and it will evolve into porygon 2
Trade it whilst its holding an Up-Grade
you give it to porygon and trade it and it evolves into porygon2
In Pokemon Platinum (I don't know about Diamond and Pearl), Porygon is located in a house directly behind the Pokemon Center. If you want to evolve into Porygon 2, trade it holding a Up-Grade, and if you want to evolve Porygon 2 into Porygon Z, trade it holding a Dubious Disk. I do not know where htese items are found. If you want to get Porygon the harder way, use Pokecheck.
Have a Porygon hold it and trade it.When the other person gets it, it will evolve into a Porygon-2.
To evolve Porygon in Pokemon Platinum you need to trade it while it is holding the Up-Grade item. This will evolve Porygon into Porygon2. If Porygon2 is traded while holding a Dubious Disc it will evolve into Porygon-Z.
you get a poragon in a town a guy in a house gives you one
