Hi Julio,

thank you for reaching out to us, and for taking interest in upgrading your AmeliaI apologize for the later response as we don't work on weekends.

You can upgrade any time - just let me know the email address you used to purchase your Basic Lifetime licence.

Then we will contact Paddle, our reseller, to charge you only the difference between your current and your new licence.

You can check the pricing here, however, please bear in mind that you will only pay the difference between the licences.
