give it a dubious disk and trade it
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
Porygon2 evolves by trading with a Dibious Disc

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.
Give it to a Porygon and trade it. It will evolve into Porygon2.
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 have to trade the Porygon 2 holding an item called "Dubious Disk" to a friend. It should evolve like any other trade-evolving Pokemon.
It evolves Porygon to Porygon2 through trade.Dubious disc will then change Porygon2 to 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.
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
Attatch it to Porygon2 and trade it- it evolves into PorygonZ
