Once you complete the main storyline of the Pokemon Sword and Shield's Isle of Armor DLC, you are rewarded with the Polygonal Pokemon itself, Porygon. While getting the Pokémon itself is straightforward, you'll need to do some outdoor adventure for a chance to evolve it. Here are the ways you can grab the Upgrade and Dubious Disk items to evolve Porygon in Pokemon Sword and Shield's Isle of Armor DLC.
How to get the upgrade and questionable disc and evolve Porygon in the Isle of Armor from Pokemon Sword and Shield
First we will find the upgrade in the wild area. Start in the warm-up tunnel and exit towards Training Lowlands. On the left between the beach and the entrance to the cave are some rocks. The upgrade is on the floor over there. If you don't want to take the item out yourself, you can craft it using the Cram-o-matic in the Master Dojo using Yellow Apricorn, Big Nugget, Big Mushroom, and a Star Piece.
Next, you're going to want to evolve your Porygon. Make him hold the upgrade and trade it with a friend who will give it back to you and you will have Porygon2.
Now that you have a Porygon2, you will need the Dubious Disk to upgrade it. The article is placed on a small patch of sand in the ocean at the extreme south of the Isle of Armor in the training sea. You can see exactly where with the video below.
Make your Porygon2 hold the questionable disc and swap it again with a friend who will return it to you. Do it and now you will have his final stage, Porygon-Z.
