Can Cross Sellings be exported?

Under "Settings > Import / Export" you will find the Shopware standard import / export. There is a profile "Default cross-selling". You can export cross-sellings with this profile. You can find the documentation for this at https://docs.shopware.com/de/shopware6-de/einstellungen/importexport. If you want to add the fields (layout and position) inserted by ACRIS, you can simply duplicate the Shopware profile and insert two additional fields "acrisCrossSellingDisplay.crossSellingDisplay" and "acrisCrossSellingDisplay.crossSellingLayout".
