it doesnt matter, the existing sancts will be deleted and replaced with random ones. to be able to transfer your dawn needs to have at least 9 stars. thats why i would suggest if you have the coins to transfer from kahn to dawn first then build up dawn and then transfer back to khan. that way your khan will end up with 5 or 6 stars. dont remember exactly how many will be lost, but someone posted it before. i believe for the 8 star transfer you will loose 2 and have 6 on dawn who will loose 1 when transfering back and lets you end up with a 5 star kahn but i might be off by a star
