hallo,
One of my clients has an old vrtuemart 1.1x vesion and we want to use eshop for his new site. Is there any way to implement the products into eshop?
EShop has the function to migrate data from Virtuemart 2.x into EShop. So if you can upgrade / migrate Virtuemart 1.x to 2.x first, then you can migrate products from VM 2.x into EShop.
