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.
5th grade
It doesn't work
It is Impossiple to catch Porygon 2 in Pokemon soul silver, and heart gold. The only way to obtain Porygon 2 in Soul Silver, and Heart Gold, is to trade a Porygon holding the Up-Grade with a friend, or with yourself. You can find the Up-Grade at the Silpho Co. Building by talking to the people on the first floor.
The cleanse tag helps to prevent from being attacked from wild pokemon. Is does work.
The only known Pokemon to evolve using the up-grade is porygon. It will evolve it into porygon2.

An Up-Grade is an item that evolves the Pokemon Porygon when Porygon is traded while holding it. Porygon evolves into Porygon 2.

yes with the up-grade
In Pokemon Platinum, Porygon-2 can evolve into Porygon-Z using the Up-Grade. I do not believe it serves any other purposes.
Get a porygon from the gamecorner its 9,999 coins and then have it hold the up-grade then trade it to a friend and take it back it will be porygon2!
