AttributeError: 'Customer' object has no attribute 'status'` while trying to restore backup from v6 to v7

I was trying to restore backup from v6 to v7 and got the following error. I followed instructions from here. Any idea how can I solve it or follow any easier way to migrate data from v6 to v7 in a fresh installation?

@mar: I believe there is no way to restore backups made for v.6 against an instance of v.7. Thus the errors you reported are no way to trap.

You may want to consider a few other options

  • upgrade of your ERP Next replica (code and data) to v.7 using bench update (this may lead to errors , depending on the extent of customization in your copy of ERP Next - therefore trying this on a separate testing/staging server will be wise before you make your call on GO with it in production)
  • export of your v.6 data into csv files and then importing them to v.7 instance using either Data Import tool or bench import-csv command
  • writing a custom python script to import your data into v.7 instance, using Frappe API
