Upgrades are part of your maintenance cost. If you've been paying that, then you should be able to request an upgrade. If not, you'll have to ask them if you need to repurchase or pay for the maintenance years you haven't paid yet (would be cheaper this way if you are less than 5 years out of your maintenance contract expiration).
