You can up- or downgrade to another price plan at any time (with the exception of add-ons). The change takes immediate effect. With upgrades, you pay the difference on a pro-rata basis. In the case of downgrades, the current billing cycle will be based on the old price.
To change your subscription, proceed as follows:
