Forum:Transfer character from one profile on a 360 to another profile on a different 360

i've been playing boarderlands at my friends house on his 360. hasn't been an issue because we always either play at his house, or he'll bring his HDD to my house, but he's moving next week and we would like to continue playing with our current characters.

i have his HDD and the game here at my house now. i'm planning on updating both to the latest software so i can use a USB flash drive for save data.

my gamertag on my 360 is different then the profile i set up on his. can i transfer my character to my gamertag on my 360?

if so any advice or instruction is very much appreciated.
