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 it whilst its holding an Up-Grade
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.
The Up-Grade Evolvs Porygon When You Give It To It And Trade. You Can Get Porygon From A Woman In Veilstone. When You Get A Porygon2 (If You Have It) Give It The Dubilous Disc And Trade Again And You Get Porygon Z. Hope I Helped :)

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.
I think you need to trade it. But I don't no
