What is the problem: Content references in product and other config pages not getting updated from /etc/commerce/products.. to /var/commerce/products... on migration from AEM 6.3 to AEM 6.5
Content properties of our content still contains the old /etc/commerce/ values. The product data got migrated successfully from etc/commerce/products to /var/commerce/products
The references for we-retail product pages got updated for new path.
References should be adjusted. Can you check your upgrade.log from that time and check if you have statements like this:
* Found NNN references
* Updated references
* No references found
