How to Tranfer Heirlooms to different Battle.net

I had my whole account transferred to another battle.net and of course Heirlooms are account bound
you cant transfer them when they are on you.. So what I did was deleted them.

1. Delete Heirlooms
2. Transfer
3. Item restore
4. ????
5. Profit

You now have your old heirlooms on your new account


I didnt pay for a character transfer I just asked if blizzard could "reconcile" my accounts.
So they moved a whole license to another battle.net which i didnt have any heirlooms.
I then restored my heirlooms, and bam new heirlooms on new account.
