Why does the new voucher wipe out remaining days on my old voucher?

When you activate a voucher the current subscription will end, and the new one will begin. The remaining part of the existing subscription will be added to the new subscription as specified in the voucher and a new end date will be determined. If the new subscription allows for a larger number of users and/or IQs, a pro rata calculation will be done to determine the new end date.
