yes you can !
Well at least you can upgrade from any silverfast version to any other version we have without having any loss regarding a former license.
You can do this directly in our webshop as following:
to learn pricing for an upgrade, please go to our website, follow the "Store" link, and proceed your purchase as if you'd wanted to buy a new product.
http://www.silverfast.com/show/store/en.htmlPlease note the sentence next to the product selection:
"If you already got a SilverFast product, you might be eligible for a discount price for a new version by clicking here."
Follow the instructions and keep the serial number for your current product ready to calculate the upgrade prices.
