This error occurs because Salesforce requires that the value of Quote line item matches one of the price book entries and in your case it doesn't.
The best solution is to create a price book entry that would match the product that you are migrating.
For example, let's assume that your Quote line item contains the value "Import2 package", but in your price book there's no such entry as "Import2 package". Therefore Salesforce returns this error. To resolve this error, you should create the price book entry "Import2 package".Y ou can read more about products, price books and quote line items on Salesforce help portal.
