I would just use the solder that's already on the board. Just heat the contact with your iron until it's loose, and then grab it with tweezers and lift it away. Set it in position on the other board and hold it in place with the tweezers while you heat it with the iron until the solder melts. Remove the iron and continue to hold it in position until it cools and the solder hardens (probably less than 10 seconds) and you should be good to go.
