The perpetual keycode will not expire. If your license has been converted to the perpetual license there is no longer a need to renew your license. However, if your keycodes have cease to work you will need to submit an order for a new license. This will convert your current license to the perpetual license. The only charges after this point would be for any upgrades you may choose to purchase.
Upgrades require purchase in the order they are issued.
Version upgrades are not mandatory, however. If your product is satisfactory to you and there's no need to upgrade, you will not incur further charges.
