Hello! I wanted to know if I buy a PERSONAL plan, and then I want to buy a BUSINESS or PRO plan, will I need to pay extra or pay the full cost for each plan?

Я могу на версии Designer App Pack онлайн конструировать свой сайт? Что такое Online Builder в пакете App Pack? Чем отличается пакет приложений в этих двух подписках?
