Steps for Diamond and Pearl: Get a Porygon either migration or Mr.Blacklots garden in Hearthome City. Get an up-grade from Prof. Oak in Eterna City. Then trade Porygon holding it and you get Porygon2. Give porygon 2 the DUBIOUS DISK as a hold item. You get a Dubious disk near the Battle Zone. Trade whilst hold item is DDisk and Porygon-z
Steps for Platinum
Obtain lv 25 Porygon in Veilstone City from a random man. Get up-grade in eterna city from Galactik Warehouse. same trading method. Then DDisk is in another Galactic warehouse and do the same trading method
porygon evolves by trading it with a upgrade then trade with dubios disk. enjoy your porygonZ!
You cannot. Trade with UpGrade to get Porygon2. Trade Porygon2 with Dubious Disk to get PorygonZ, but you have to trade either way.
You have to trade the Porygon 2 holding an item called "Dubious Disk" to a friend. It should evolve like any other trade-evolving Pokemon.
you have to trade it while its holding an up grade item
It evolves Porygon into Porygonz.
Porygon-Z is the final form of Porygon (and Porygon2). To evolve Porygon to Porygon2, trade it while it holds an Up-Grade item. To evolve Porygon2 to Porygon-Z, trade it while it holds a Dubious Disc item.
Porygon does not evolve at a given level: you have to trade it while it is holding the Up-Grade to evolve into Porygon2. Then trade that while holding the Dubious Disk to get a PorygonZ.

You can give the Upgrade to Porygon and then trade it to a friend to make Porygon evolve into Porygon2, in order to evolve Porygon2 then give a Dubious Disc to Porygon2 and then trade it to someone and it'll evolve into a Porygon-Z.

It evolves Porygon into Porygonz.
I'm assuming you mean Porygon. Porygon evoles into Porygon2 then into PorygonZ. It evoles into both of them by being traded with an item. Porygon=porygon2 traded w/ upgrade, Porygon2=PorygonZ trade w/ dubious disk
Give it to a Porygon and trade it. It will evolve into Porygon2.
give porygon (or possibly porygon 2) dubious disc ( i think you nick it from galactic hq) and trade him.
