How do you evolve Porygon into Porygon2 in Pokemon Pearl?

Answer 1

1. Talk to Professor Oak in the Southwest of Eterna City after beating the Elite Four. He will give you the Up-Grade.
2. Then, let PORYGON hold the Up-Grade and trade it to another person. It will evolve after trading. After this, trade it back to your own game.

Answer 2

Trade Porygon while it's holding Up-Grade and it should evolve into Porygon2 (P.S.: To evolve Porygon2 into Porygon-Z, trade Porygon2 while it's holding the Dubidous Disk, and Porygon2 should evolve into Porygon-Z)

Answer 3

Give your Porygon2 the item dubious disc to hold and then trade with one of your friends. It will evolve into Porygon-Z.
