I have installed ERPNext V12 with some custom fields exported as a fixtures to the custom app.
After switching to V13 I ran bench update as suggested and got this error saying that custom field already exists.
frappe.exceptions.ValidationError: A field with the name 'valuation_rate' already exists in doctype Quotation Item
Full error log:
