Yes, the old affiliate should be credited even if a new affiliate referred the same player again. After all it’s the same casino just different software.
Unless of course, the reason the old player is returning is because he/she will be treated like a New Player (Sign UP Bonus and New Loyalty Program) then the new affiliate should be credited with the referral.
Greg,
How exactly to you plan on converting the old players to the new software. What methodology are you employing?
Thanks,
