I bought your extension for Magento 1.x.x. However, recently, we have decided to start over with a Magento 2 setup.
Thus, I would like to know if there is a way to “upgrade” the existing license to the Magento 2 version of your module.
Could you please purchase our Magento 2 module version for your Magento 2 site?
If you need any further assistance, please feel free to contact us via email firstname.lastname@example.org
We'd like to help.
