In fact, it is very easy. There are no special conditions. You just have to follow these steps:
- Proceed to purchase the upgraded license (Professional or Business license)
- Activate your current domain with the new license. (important if you don't want to get an unwanted message when we proceed with the refund)
- Contact us and let us know that you want to upgrade. Try to include in your email your licenseKey. This will help us identify your product.
- We'll then proceed to refund you the previous purchase.
Notice however that you won't be eligible for a refund if your previous product was purchased more than 30 days ago.
Also, when you upgrade to a Professional license, you'll have one domain less than usual as the old one will get moved to your new license.
