You save first, at the Traveler NPC in red on the left side of town near the Inn.
There should be an NPC to the left side of town, on a stairway facing left. He is between the Magic Shop and the Armor/Weapon Shop.
Talk to that NPC and he should say something about occasionally getting villagers to your town. He finishes the conversation by saying something about putting the word out to his friends, seeing if anyone is willing to help your town (something like that, don't have the game with me atm). Then you should see an update in your bottom screen/town menu. Not sure if it matters, but I don't go to the village just yet.
First go back to the Traveler NPC, choose Save BUT DO NOT SAVE YOUR GAME and instead, choose Go To Main (or w/e it is that takes you to the main menu). Then once there start your save file. Your update/villager should pop up in your village. Go back to the NPC that gave it to you, he should say the same thing, give you another villager, go back to traveler, exit to main menu via him without saving, repeat.
You can only transfer 20 villagers from the Demo to the full game so keep that in mind. I did 21 I think? It will make it easier to get everything upgraded for that Item Set which also will transfer.
Note: I had already activated the Turtle Boss Quest myself when I found out about this. Turns out after you complete that this NPC will be back on the steps. I don't know if it matters that I never talked to him before that though, so your mileage may vary if you already had. If it really matters, it wouldn't take too long to delete your save and start a game over to do this if you really want that 20 villager transfer and can't get it via Street Pass.
