Product Attribute Migration from 7.5.3 to 8.1
A customer has migrated from version 7.5.3 to version 8.1. The upgrade automatically runs a repository upgrade but this did not correctly convert all the product definition attribute property values such as the default value and required flag. The problem is specific to products on 7.5.3 where the class attribute property values were changed on the 7.5.3 product definition in the Product Admin>More Info>Dynamic Attributes view. These values are now different in the 8.1 Admin Product>Product Definition>Workspace Version>Attributes tab.
A large number of products now have different attribute product properties between the 7.5.3 and 8.1 applications. How can the 8.1 application be updated automatically to save the manual entry of these attribute properties?
