(adsbygoogle = window.adsbygoogle || []).push({}); Well my mate wanted the CoWaW map packs that I have and he hasn't got the money to buy MSPoints so I had a crack at transfering and it worked!

Heres my method:
1. Migrate your account to your mates HDD
2. Sign in on your account
3. Press the Xbox Guide Button
4. Goto 'Settings'
5. Goto 'Account Management'
6. Goto 'ownload History'
7. Locate the DLC and select it by pressing 'A'
8. Click 'ownload Again'
9. Wait for the download to finish.
10. Sign out of your account
11. Sign onto your mates account
12. DONE!

I hope this works for you.

License transfer and cache it?

It works.
