Do you want to change plans while you already settled down for a plan? This is possible. When upgrading your plan, you do not need to pay the full price of the new plan. The price is decided on how long you are on the remaining plan. The time you are still on the old plan will be taken off the price of the new plan. This counts for monthly as well as yearly plans.

NOTE: Downgrades take effect when your current license term expires.

For example, when you rebuy the same license for a year plan it will automatically update the time and makes you only pay those extra days.
