Alright, Thank you. But i do that, create a new system, transfer all the raids, it doesnt seem like dkp spent is divided by dkp earned. on the current standings page it still shows the old dkp totals, and not the new divisioned totals. And I would need customs fields like effortpoints, gear points, and priority, correct?
You don't need to create a new system, you just need to edit the existing one and make it use Division.
As for the custom fields, "effort Points" are no different than "Earned Points" and "Gear POints" are no different than "spent points" so there's nothing custom you need to do.
