1 You cannot unbind all of your VIP accounts after you have bound your accounts in the VIP Center.

2 After your VIP Level has been upgraded, all the VIP accounts you have bound will become unbound, automatically. You can choose to bind other accounts, or re-bind your original accounts, again.

3 Once you meet the requirements, your account will upgrade after 02:00 the second day.

4 You can bind a higher level VIP to an account that has already been bound to a lower level VIP. For instance, if the account is bound to a Lvl 1 VIP, then you can bind a Lvl 2 VIP to it without waiting for it to be unbound when VIP level upgrades.
