Thank you.
Are you trying to use store import? Why wouldn't you just upgrade rather than store import?
I am not importing. Started upgrade and stuck. Seems created backups but not upgraded and I start over and getting this error. How I can fix this issue?
Contact CS-Cart support team. Looks like something wrong in the database structure
